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.

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.

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.
