    Can CBD Thicken Hair?

    CBD products are essential for thickening hair. This article focuses on how the oil help with hair loss, the side effects of its use, how it works in the body, and the various treatments available for hair loss.

    Cannabidiol, or CBD, is one of the over 100 cannabinoids isolated from hemp. Hemp has very little of the psychoactive compound THC, typically 0.3% or less. THC levels below this percentage are considered safe for consumption.  Corroon et al. (2019) opined that the human endocannabinoid system (ECS) is a significant regulatory network that interacts with CBD to dispense therapeutic effects. The ECS regulates several physiological functions, such as mental processing, rest, stress response, immunological function, pain signaling, and hormone balance. CBD oil has shown promise in treating a wide range of medical conditions, including anxiety, sleeplessness, depression, epileptic seizures, inflammation, and pain. In addition, CBD has positive effects on the skin, hair, and scalp.

    Does CBD Oil Help with Hair Loss and Thickening?

    CBD extracts added to carrier oils promote hair development over a period, which explains why CBD oil has been linked to re-growing and strengthening hair following hair loss. The cannabis derivative may also help people get to sleep and feel less anxious. Since stress is linked to increased hair loss, reducing stress in one's everyday life may promote hair follicle regeneration.

    What Are the Side Effects of Using CBD Oil for Hair Loss?

    White (2019) observed that CBD is risk-free for human use. However, oils that have not been authorized by the FDA are not subject to regulation; their quality might vary. Common side effects include diarrhea, changes in appetite, and weight among other side effects. Some drugs may also react negatively to CBD. So, it is important to talk to your doctor before starting a CBD regimen.

    3-4 Mg of CBD Once a Day Brings 93.5% Increase in Hair thickening and Growth

    Follicular shrinkage in pattern hair loss caused by systemic androgen and hereditary factors characterizes androgenetic alopecia (AGA). Though it often manifests in one's 30s or 40s, the development of this condition occurs shortly after puberty. Hair loss affects over half of Caucasian males and one-fifth of Caucasian females; however, it is less severe among Asian and black populations. According to Wolff (2020), hair thinning and loss manifest differently in men and women; in men, it causes baldness on top of the head, while in women, it often manifests as more distributed thinning while the hair at the front of the head remains unaffected. A recent study showed that the effects of CBD on human hair are strictly dose-dependent. Hair loss increases if you don't take medication as prescribed. Researchers found that after 6 months of administering topical hemp extract containing 3-4 mg of CBD once daily, hair growth had increased by 93.5% in 35 participants (28 men, 7 females) with androgenetic alopecia (AGA). There was 10.78% CBD and 0.21% THC in the extract used to make the topical, which was derived from ultra-finely ground flowers of Cannabis sativa with a high CBD content.

    How Does It Work in the Body?

    CBD's new effects on hair follicle elongation and keratinocyte activation via the endocannabinoid system (ECS) are particularly intriguing. According to Telek et al. (2007), CB1 receptors are highly expressed in hair follicle cells, and stimulating these receptors stop hair loss. TRPV1 receptors have been identified as the target for hair loss in rodent research. Phytocannabinoids like THC and CBD convey messages to TRPV1 receptors. THC has been demonstrated to dose-dependently impede hair shaft elongation, reduce the proliferation of hair matrix keratinocytes, induce intraepithelial apoptosis, and cause premature hair follicle regression. In contrast, CBD has been hypothesized to have therapeutic effects through TRPV1 receptors. According to the findings, cannabidiol (CBD) and other CB1 antagonists can stimulate hair growth, whereas THC and other CB1 agonists can control excessive hair growth.

    Other Treatments for Hair Loss

    Increasing your intake of dietary iron and zinc could suppress hair loss. There is some evidence that vitamin deficiencies might cause thinning of hair or complete baldness. Common causes of hair loss include stress. Some studies suggest that practices like yoga and meditation might stimulate new hair growth. Adopting a healthy eating pattern could also inhibit hair loss. Some studies have linked eating meals high in protein and omega-3 fatty acids to good hair. Learn more about does cbd eye cream work?


    CBD oil has therapeutic promise for various medical issues, including hair loss. While CBD products vary, they have common therapeutic effects when used appropriately. As discussed earlier, stress is linked to increased hair loss; reducing stress in one's everyday life may promote hair follicle regeneration. CBD products for hair loss need prescriptions to prevent further damage to the user. Seek medical advice to get the required version of CBD for your hair condition.
