Does CBD Oil Help With Hair Growth? Benefits of Using Hemp Oil For Hair
Hair loss is a common problem affecting the entire population in varying degrees, with up to 100 strands of loss per day considered normal. However, excessive hair loss is not typical and may have a genetic, hormonal, or stress-related background.
People try different things for hair loss, from special shampoos to hair loss treatments and even transplants.
But did you know that a compound from the cannabis plant known as CBD may just be the perfect ingredient for a perfect hair day? Studies have demonstrated that CBD-rich hemp extracts suspended in carrier oils can take care of your mane while also nourishing your hair from the inside — making it stronger and thicker over time.
And the best part about using CBD oil for hair loss is that it won’t make you high, unlike marijuana products. Today, we’re going to explain what CBD is, how CBD oil can help with common hair issues — from dry scalp to chronic inflammation — and give you our recommendations on the best CBD products for hair care.
Whether you’re a man or woman struggling with hair loss, we’re here to help you out with a decent portion of scientific research!
CBD Oil for Hair Loss: Everything You Need to Know
In this section, we’ll cover the benefits of CBD oil for common hair issues to help you understand how it can contribute to a healthy scalp and strong, nourished hair.
CBD Oil Can Prevent Hair Loss By Providing Restful Sleep and Less Stress
We all live in stressful times where peer pressure and expectations from society can wreak havoc to one’s well being. Our fast-paced life and continuously high levels of stress lead to excessive production of cortisol, which is a hormone that triggers the “flight or fight” response when you’re in a dangerous situation.
High amounts of cortisol in the body have been associated with hair loss on top of weight gain and sleeping difficulty. When you have less cortisol in your system, you have higher chances of getting more restful sleep, preventing hair loss.
CBD has been shown to reduce anxiety, improve sleep patterns, and help with stress management in day-to-day situations, therefore potentially reducing the risk of hair loss.
CBD Oil Can Reduce Inflammation
Chronic inflammation can be devastating for your general health, but it also significantly worsens the condition of your hair’s health, including its growth.
CBD can suppress inflammation in the body, promoting a healthy environment for hair to grow on the scalp; it can also reach sebaceous glands that secrete sebum to lubricate hair in follicles, preventing them from drying out.
CBD Oil Improves Blood Circulation
Better blood flow offers many benefits for the body, especially around hair follicles, encouraging hair growth. Since CBD increases cerebral blood flow, it brings more nutrients to hair follicles while removing harmful toxins and thus allowing hair to become healthier and stronger.
CBD Oil Supports Homeostasis
As mentioned earlier, CBD can interact with the endocannabinoid system, which is a major regulatory network in the body involved in a number of biological functions, from cognition to pain to appetite and new cell growth.
CBD is known for its ability to modulate the functioning of the endocannabinoid system, which can have a positive effect on your body’s potential to maintain a healthy state of homeostasis. This term refers to a state of balance between physiological processes in the body, including hair growth.
How to Use CBD Oil for Hair Loss?
CBD oil comes in a variety of products, from sublingual drops to edibles, vapes, and shampoos. If you want to maximize the benefits of CBD oil for hair loss, we recommend that you support your scalp treatment with organic hemp seed oil for the extra content of essential fatty acids, proteins, vitamins, and minerals. This way, you will provide your hair with all-around care.
Below we explain how to use CBD oil for hair loss and other scalp-related issues.
CBD Oil for Dry Hair and Scalp
If your hair starts to look like straw and feels dull lately, it may be time to introduce CBD oil into your hair care routine. CBD oil and hemp oil can stimulate the formation of new cells on the scalp and enhance the growth of new hair. Every single strand of hair is made out of protein, and because CBD oil contains 21 amino acids, using CBD oil or shampoo can help strengthen and moisturize your hair.
CBD oil is also rich in antioxidants, which can help to protect your hair against environmental factors, keeping them strong and healthy even in harsh conditions.
If you suffer from dry, itchy scalp, you can use CBD oil to reduce inflammation from the inside or add a topical to approach the problem locally. A healthy scalp is an answer to healthy hair, a combination of CBD oil, CBD cream/shampoo, and hemp seed oil can help you bring the scalp back to its normal state and help you get rid of itchy, flaky scalp.
Not to mention a powerful moisturizing effect due to the presence of the fatty acids.
CBD Oil for Hair Growth
Life isn’t always fair. Some people can easily grow their hair down to their waists while the rest of us have problems with growing our hair stronger and thicker. Fortunately, regular use of CBD oil can promote healthy hair growth with Omega-3, Omega-6, and Omega-9 fatty acids. When absorbed by the scalp, they help stimulate hair growth, resulting in thick, long, and lustrous hair.
Best CBD Oils for Hair Loss in 2022
When buying CBD oil, you shouldn’t act on the spur of the moment. It should always be a well thought out decision based on thorough research rather than advertising slogans. If you don’t have the time to dig deeper into the quality criteria for CBD products, we’ve compiled a list of the best brands that offer CBD oil for hair loss and more. We have selected the top 5 brands from over 40 companies that we’ve reviewed in 2022 so far.
1. Royal CBD (Best CBD Oil for Hair Loss)
Get 15% off all Royal CBD products. Use code “CFAH” at checkout.
|Potency||250 mg –2500 mg|
|Available Flavors||Natural, Berry, Mint, Vanilla|
|CBD per serving||8.3 mg – 83.3 mg|
Why Royal CBD is the Best CBD Oil for Hair Loss:
Royal CBD is a premium Nevada-based brand established by a group of friends with a goal to raise the quality standards regarding the production of CBD oils and customer service. This relatively new company offers a simple product line up consisting of full-spectrum CBD oil, softgel capsules, THC-free gummies, and two types of broad-spectrum topicals.
Royal CBD oil comes in four different concentrations, including 250 mg, 500 mg, 1000 mg, and 2500 mg. You can choose from three flavored options, save for the highest potency which is only available in the unflavored version to maintain the potency of CBD. All of the Royal CBD products are made from US-grown organic hemp and extracted with supercritical CO2. This method of extraction ensures that the plant’s original chemical profile is preserved due to lower temperatures. The CBD oil has been suspended in food-grade MCT oil from coconut to enhance its bioavailability and provide the body with additional benefits, such as stable energy for the brain and support for cardiovascular health.
Fortunately, my hair is in good shape, but I sometimes have an itchy scalp when I’m working from dryer climates, so I always have a bottle of the 1000 mg oil with me. It helps reduce the itching and I have a feeling that it also moisturizes the scalp. No scratching, no pain — if only CBD oil was easier to wash down from hair!
- Sourced from non-GMO, Colorado-grown hemp
- Extracted with supercritical CO2
- Contains full-spectrum CBD
- Available in 4 strengths and 3 flavored options
- Up to 2500 mg of CBD per bottle
- Lab-tested for potency and purity
- 30-day money-back guarantee
- Slightly more expensive than the competition
- No vape products available
2. Gold Bee (Best Organic CBD Oil)
|Potency||300 mg –1200 mg|
|Available Flavors||Natural, Honey|
|CBD per serving||8.3 mg – 33.3 mg|
About Gold Bee:
Gold Bee is my second-favorite CBD oil for hair loss. As you can see, the podium is taken by two Nevada-based brands. This company is a true maverick among other manufacturers due to the honey flavor in its CBD oil, which the company makes from Colorado-grown, organic hemp plants. Both the quality of ingredients and the honey flavor are award-winning. The CBD oil tastes surprisingly neutral, with delicate yet noticeable notes of honey. There’s no tart sensation in the throat after swallowing, probably because of the lower potencies.
Speaking of which, Gold Bee scores the second place because it offers a limited potency range compared to Royal CBD. There are no high-potency oils in Gold Bee’s collection. Other than that, it’s a great brand that offers premium products at reasonable prices.
- Made from US-grown organic hemp
- Contains the full spectrum of cannabinoids and terpenes
- Up to 33 mg CBD/mL
- Good potency range for new users
- Lab-tested for CBD content and purity
- No high-potency oils
- Honey is the only flavored option
3. CBDPure (Top Transparency)
|Potency||100 – 1000 mg|
|CBD per serving||3.3 mg – 33.3 mg|
CBDPure first started in 2016 with the goal of making premium CBD oils from organic hemp. Considering what their audience says about their products, the guys at CBDPure must be doing a good job chasing that goal.
Similar to Royal CBD and Gold Bee, CBDPure sources its hemp from Colorado, where the plants are grown without any harmful pesticides or growth boosters. The company provides third-party lab reports for its products on request to leave no doubts that the CBD oil it offers meets the quality and safety criteria.
If you’re just starting out or if you need a product to support your hair growth and revitalize the scalp from the inside, this company is an excellent choice. Although CBDPure specializes in making low-strength CBD oil, these are real full-spectrum products that could proudly compete with some high-potency products on the market — most of which are more expensive.
You can tell that the quality is there simply by looking at the oil’s color. CBDPure’s products are amber gold, which indicates CO2 extraction and proper filtration. The CBD in the oil has been decarboxylated to maximize the product’s potency.
Although the CBD oils from this brand taste better than traditional hemp oils, they still leave an earthy aftertaste. Plus, they’re also less affordable in the long run compared to the two above brands.
- Sourced from Colorado-grown organic hemp
- Extracted with CO2
- 4 strengths to choose from
- Lab-tested for potency and purity
- 90-day return policy
- No high-potency oils
- Only two forms of CBD available
- Priced higher than competitors
4. Hemp Bombs (Best CBD Isolate)
|Potency||125 – 4000 mg|
|Available Flavors||Natural, Acai Berry, Orange Creamsicle, Peppermint, Watermelon|
|CBD per Serving||4 – 133 mg/mL|
About Hemp Bombs:
Based in Tampa, Florida, Hemp Bombs is a manufacturer with a well-established reputation of the best isolate-based CBD oils on the market. This is quite an achievement considering the company started out in 2016. One of the great things about this brand is that it controls every step of the manufacturing process of their products, from extraction to packaging.
Hemp Bombs CBD oil comes in a very wide range of strengths. They start at 125 mg and may contain up to 4000 mg of CBD per bottle. The highest potency provides a massive dose of 133 mg in each milliliter. However, this brand doesn’t feature any full-spectrum CBD products. You can only choose between broad-spectrum CBD and CBD isolates.
The first type of CBD contains all the non-psychoactive cannabinoids and terpenes, but with no traces of THC, so you’re getting some part of the entourage effect. CBD isolate contains nothing but pure CBD; it’s a good option if you undergo drug tests or just want to benefit from CBD alone.
- Made from organic hemp
- Extracted with CO2
- Third-party tested for potency and purity
- Up to 4000 mg of total CBD
- 5 potency options to choose from
- Flavored with synthetic ingredients
- No synergy from other cannabinoids and terpenes
- Most people don’t need so much CBD oil in their routine.
5. CBDistillery (Most Affordable)
|Potency||250 mg – 5000 mg|
|Potency||8.33 – 166 mg/mL|
CBDistillery is one of the most recognizable brands in North America. The company has a stellar reputation among customers, mostly thanks to its transparency and skipping gimmicks. CBDistillery is committed to education and maintaining high-quality standards. The brand is certified by the U.S. Hemp Authority (USHA) after passing a third-party audit and meeting strict standards regarding labeling, ingredients, and the Food and Drug Administration (FDA) compliance.
CBDistillery uses non-GMO industrial hemp grown on open-air farms in Colorado, Kentucky, and Oregon. The company’s CBD oil is available in full-spectrum and broad-spectrum versions to cater to different types of CBD users. Users can choose between 5 strengths, with up to 5000 mg of CBD per bottle. The oils are extracted with supercritical CO2 and have been granted the current good manufacturing practices (CGMP) certificate.
This is the most affordable company that I’ve ever come across. Even though CBDistillery’s products aren’t made from organic hemp, the price-to-quality ratio makes them the best in their price range.
- Available as full-spectrum or broad-spectrum CBD
- 5 strengths to choose from
- Up to 166.6 mg of CBD per mL
- Third-party tested for CBD content and purity
- Very affordable
- Sourced from non-organic hemp
- No flavored oils
What is CBD?
CBD stands for cannabidiol, one of over 100 compounds from hemp identified as cannabinoids. Despite coming from the same plant family as marijuana, hemp contains only a trace amount of THC — usually 0.3% or less. There’s no risk of getting high off of hemp-derived products as long as their THC content is double-checked by a third-party laboratory.
CBD interacts with the human endocannabinoid system (ECS), which is a major regulatory network within our bodies. The ECS controls a wide range of biological processes, including emotional processing, sleep cycles, stress management, immune response, pain signaling, neuroprotection, appetite, body temperature, hormonal balance, and more.
This interaction leads to a plethora of health benefits. Research shows that CBD oil may help with anxiety, insomnia, major depressive disorder, epileptic seizures, inflammation, pain, and more.
As it turns out, CBD has also several benefits for the skin, including the scalp and hair.
However, before we elaborate on the above benefits, let’s make sure that you know the difference between CBD oil and hemp seed oil.
CBD Oil vs. Hemp Seed Oil
When shopping CBD online or locally, you’ll see products like CBD oil and hemp oil being placed next to each other, which may create confusion. New users often use these terms interchangeably to describe one type of product, but this is an oversimplification.
The difference between CBD oil and hemp seed oil is simple.
CBD oil is extracted from the flowers of mature hemp plants. The flowers contain resinous glands where cannabinoids such as CBD are secreted. CBD oil is typically made using CO2 extraction to pull the beneficial compounds from the plant without using additional heat and solvents. Once extracted, the CBD is suspended in a carrier oil for increased volume and better bioavailability. The carrier is usually a food-grade oil such as hemp seed oil or MCT from coconut.
Hemp seed oil comes from the plant’s seeds; they are a popular superfood due to their dense nutritional content. Hemp seeds are packed with essential fatty acids, complete protein, vitamins, and trace minerals — but they don’t contain any cannabinoids.
Long story short, the hemp seed oil is a great carrier and a decent source of nutrients, but there’s no CBD in it.
You can, however, combine these two products to maximize the results of your hair loss treatment.
Let’s see how CBD oil can strengthen your hair and prevent them from falling out.
How to Choose the Right CBD Oil for Hair Loss
Choosing the right CBD oil for hair loss can be difficult considering the abundance of brands and products on the market. It seems as if every company out there was selling CBD oil in some form to capitalize on the booming market. The CBD industry is largely unregulated because the FDA refuses to acknowledge hemp-derived CBD as a treatment for any health condition despite its wide range of science-backed benefits.
There’s a lot of great companies selling premium products that can improve your skin’s health, but there’s an equal number of companies preying on the lack of education among new customers.
Here’s how you can protect yourself from sketchy products:
- Check the hemp source. Hemp plants are bioaccumulators, meaning they can absorb every substance from the soil they were planted in. The best CBD oil for hair loss comes from organic, non-GMO hemp that is grown locally under the sun and without pesticides or synthetic growth boosters. This type of hemp ensures clean CBD-rich flowers.
- Choose CO2-extracted CBD. CO2 extraction is by far the best method to produce CBD oils. It doesn’t require additional heat or solvents, so it can pull the beneficial compounds from the plant matter without hurting the environment on the way or leaving behind toxic residue.
- Opt for full-spectrum products. Full-spectrum means that the product was made using the whole plant. This process captures CBD along with other cannabinoids and terpenes, including trace amounts of THC (up to 0.3%). These compounds help your body process the CBD more efficiently, allowing lower doses to remain effective in certain cases. If you don’t have to undergo THC drug screenings at work, full-spectrum CBD oils are better than products based on single molecules like CBD isolate.
- Always ask for third-party lab reports. Outside laboratories will analyze the CBD content in your CBD oil; they will also look for common contaminants and other unwanted substances, such as heavy metals or pesticides. If you can’t see the lab reports on the company’s website, or can’t receive them on request, buy your CBD oil somewhere else.
- Avoid companies making outrageous claims about CBD. Cannabidiol is a highly versatile compound. It can help revitalize your scalp and contribute to healthy hair growth, but it won’t cure skin diseases or mend broken bones. If you see a company claiming their product is a miracle drug, this is an instant red flag.
Following these simple steps and doing your research will save you time and money.
Final Thoughts on CBD and Hair Loss
CBD is a promising compound for a variety of applications, including hair loss. While it’s highly unlikely to treat a medical hair loss condition with CBD oil, you can use it to combat a number of health problems that can disturb your scalp’s microbiome and worsen the health of your hair follicles.
If you want to maximize your results using CBD oil for hair loss, we recommend that you combine it with a topical product for a multi-angle approach. You can also add hemp seed oil to your diet or skincare routine due to its dense nutritional content for hair. Hemp seed oil is packed with essential fatty acids, proteins, vitamins, and trace minerals — all of which can contribute to a healthy strong mane.
Always do your research on any company before buying CBD oil for hair loss and make sure that your product has been tested by an independent laboratory. Only then will you protect yourself against fly-by-night companies.

CBD is the darling of the beauty industry at the moment. If you’re like us you’re intrigued by the hemp plant-derived cannabidiol. We know that CBD can benefit those with anxiety. There are also claims that CBD can smooth wrinkles, hydrate, and even get rid of acne. The scientific jury is still out on substantiating those claims, but what we do know is that CBD has antioxidant and anti-inflammatory properties. So how can those properties benefit hair? To get more information on how CBD might be able to benefit our hair and help with hair loss, we talked with Michelle Henry, MD, a board-certified dermatologist, Harvard-trained Mohs surgeon, and Cantu Partner.
Before we get into the nitty-gritty of using CBD for hair loss. We want to share the differences between CBD and hemp seed oil. These are two variations of Cannabis sativa that are both hitting the skin and hair care market. They each have anti-inflammatory properties, but they are created differently. On the one hand, CBD oil is derived from the stalks, leaves, and flowers of the hemp plant which means there are higher concentrations of CBD in its makeup. On the other hand, hemp seed oil is made from the seeds of the Cannabis sativa plant.
Now that we’ve given you that tidbit of information, it’s time to talk CBD for hair loss.
Meet the Expert

CBD is an anti-inflammatory powerhouse, so much so that it is proven to help lower pain and inflammation due to arthritis. But, how does that benefit translate to our scalp? For starters, CBD naturally boasts a high concentration of antioxidants like vitamins A, C, making it an antioxidant-rich and anti-inflammatory option. “The actual active (cannabinoid) is anti-inflammatory and can help psoriasis and eczema,” Henry tells us. “For scalp and hair issues that are triggered by inflammation such as psoriasis, dermatitis especially in women who have hair loss in women. If women patients don’t want to use traditional medicine. CBD oil can help with those issues.”
Hemp seed oil has also entered the haircare chat, but because hemp seed oil is derived from seeds it doesn’t carry as many anti-inflammatory benefits as CBD oil. However, for those that are looking to moisturize a flaky or irritates scalp, Henry tells us hemp seed oil does just that. “Hempseed oil is going to help lock in moisture in the hair and scalp. What people forget is that the scalp is an extension of the face. What’s become more popular is the skifinification of the scalp and extension of skincare, so we should use similar ingredients. Do all the things we would do on the face (moisturize, nourish) on the scalp to help with hair loss and stimulate hair growth.”
Because hair loss and irritation can be attributed to many other factors, talking with your healthcare provider about your unique concerns is the best option.
Hair Type Considerations
CBD can benefit a range of hair types. However, Henry notes that research on CBD’s ability to promote hair growth is limited. “I have not seen any studies about [CBD oil] directly stimulating hair growth. However, reducing inflammation is encouraging hair growth and protecting the hair.” We can thank Phytocompounds —antioxidant effects and antimicrobial properties— for that. When applied to our skin, the hemp plant can molecularly connect to the CB1 and CB2 receptors in our bodies and reduce inflammation—this includes our scalps. Before you run out and purchase a CBD product for your hair, there are a few things to keep in mind. As we noted at the start of the story, CBD and hemp seed oil are different. Hemp seed oil does offer up fatty acids, which are excellent hydrators of the hair and scalp. However, CBD has a higher level of anti-inflammatory benefits. So when looking at the label of products, you’ll want to be mindful of your needs and the ingredients in your product of choice. The labeling can be a bit confusing, but we hope our breakdown helps.
How to Use CBD for Hair

When using CBD oil on your hair and scalp, you’ll want to follow the same practices you would with any other hair care ingredient if you’re using a CBD-infused shampoo, conditioner, or styling product used as recommended or as often as your hair type calls for. When it comes to applying CBD oil to the scalp, six to eight drops are typically more than enough for any oil you plan to use on the scalp, and we’d apply that same cadence here.

3-4 Mg of CBD Once a Day Brings 93.5% Increase in Hair Growth
CBD demonstrated promising results in a recent case study on 35 people in the ‘Hair and Scalp’ center in Clearwater, Florida. After six months, the hair in the temporal area increased by 74.1% in men, and 55.2% in women. For the vertex, the findings show an increase of hair growth of 120.1% for men and 64.9% for women.
Androgenetic alopecia (AGA) is a condition characterized by follicular miniaturization in a patterned hair loss occurring due to systemic androgen and genetic factors. It starts immediately after puberty, but the age of onset is usually 30s and 40s. According to research, 50% of Caucasian men and 19% of Caucasian women are confronted with hair loss, while its severity is lower in Asian and black people. Men and women have different patterns of hair loss – in men, it results in baldness at the top of the head, and in women, it usually occurs as diffuse thinning, while the frontal hair is preserved. Considering that the human population is heading towards eight billion , there is quite a number of bald heads in th e world.
CBD could be a promising novel treatment for AGA, but a previous study has shown that the effects of CBD on human hair are strictly dose-dependent. Missing the exact dose, as always, could lead to the opposite effect – hair loss.
Research published in Cannabis, a publication of the Research Society on Marijuana gives some new clues about th is important dosage. A study on 35 subjects (28 males, seven females) with androgenetic alopecia (AGA) using topical hemp extract with 3-4 mg of CBD once daily has shown a 93.5% increase in hair after six months. The topical extract in question has been made of high CBD Cannabis Sativa flower ultra-pulverized into a fine powder that contained 10.78% CBD, and 0.21% THC. The results revealed that men did slightly better than women, and the vertex area did better than the temporal areas.
How does it work in the body?
As the new study conducted by Gregory L. Smith and John Satino explains, CBD works through the endocannabinoid system (ECS) and shows some novel effects on hair follicle elongation and hair matrix keratinocytes activated through ECS receptors. Stimulating CB1 receptors, which are well expressed in the hair follicle cells, leads to decreased hair loss. Rodent studies have shown that the receptors targeted for hair loss are TRPV1. The phytocannabinoids such as THC and CBD message TRPV1 receptors. It is postulated that CBD has therapeutic effects through TRPV1 receptors, and THC has been shown to dose-dependently inhibit hair shaft elongation, decrease proliferation of hair matrix keratinocytes and induce intraepithelial apoptosis and premature hair follicle regression. The research shows that THC and other CB1 agonists can be used to manage unwanted hair growth, and CB1 antagonists, such as CBD and tetrahydrocannabivarin (THCV) or cannabidivarin (CBDV) can be used to promote hair growth.
CBD for hair loss: The lucky 35
The study is a case series of adults presenting to a ‘Hair and Scalp’ center in Clearwater Florida. Adult subjects, not currently using minoxidil or finasteride were offered the opportunity to receive the hemp oil extract free of charge through Facebook advertising. The first thirty-five subjects who responded were selected. The females were ages 46-76 (average age 61) and the males 28-72 (average age 43).
The subjects were given a topical extract in a 2 oz (around 60 ml) jar once a month and advised to apply a thin layer once each morning to the areas of baldness. The subjects were advised that they could use blow dryers, conditioners, and other hair preparations. The 2 oz topical was replaced as needed at monthly visits throughout the six-month trial. The amount used varied significantly based on the area of the scalp to be treated. None of the subjects used more than 2 oz in any one-month period. The chalk-like green powder produced from the hemp flowers was infused into a lanolin base paste and natural Emu oil carrier. Each 2 oz jar contained 1000 mg of the powder or 108 mg of CBD.
The hair counts in the temporal area increased an average of 74.1% in men, and 55.2% in women. In the vertex area, the hair counts increased an average of 120.1% for men, and 64.9% for women. One-third of the patients reported some slightly increased hair discharge during the first month of treatment, this was no longer was noted at the two-month visit. Otherwise, there were no reported adverse effects.
Although the mechanism of therapeutic effects is not entirely clear, this case study supports significant hair regrowth benefits in both men and women with AGA, the scientists conclude. D efinitive research is planned.
