Hair's The Thing
It reduces itching, and has anti-aging and anti-malignancy effects, according to researchers.
More beauty brands are incorporating CBD into hair care formulations.

CBD is in the news, in tinctures, in skin care creams and even in hair care products. CBD is the abbreviation for cannabidiol, a chemical compound found in hemp and marijuana and one of the 120 cannabinoids found in cannabis. Even though it is one of the hundreds of marijuana components, CBD by itself does not cause a “high.” CBD is considered a non-psychoactive, antioxidant and anti-inflammatory compound derived from the Cannabis sativa plant. There are various reports on the versatile function of CBD, including ameliorating chronic inflammation and fibrosis formation in several tissue types.
All 50 US states have laws that legalize CBD with varying restrictions. Even though the government considers CBD in the same class as marijuana, it does not enforce against it. Cannabidiol is used medicinally as it is proven to have numerous medicinal benefits. Several pre-clinical studies on CBD formulations reveal that cannabidiol has an array of medicinal properties, including anti-inflammatory, anti-depressant, anti-tumor, anti-nausea and anti-psychotic. This makes CBD a natural remedy for several medical conditions like anxiety, nausea and seizures. CBD is also used in the cosmetic industry for problems like dull hair color, breakage, hair loss and itchy scalp. There are numerous hair and scalp care products that use CBD as the main component.
Mode of Action
Cannabis exudes a resin that contains cannabinoids. These cannabinoids have two principal components, cannabidiol (CBD) and tetrahydrocannabinol (THC). The structure of CBD was discovered in the 1960s and gained particular attention due to its lack of psychotropic activity, low abuse potential and excellent tolerability in humans. All of these characteristics made cannabidiol an ideal candidate for clinical use. Remember that CBD alone does not have any psychoactive effects, but that some CBD products may contain trace amounts of THC. That is why many military personnel are prohibited from using CBD for pain management or other conditions. Thus, one must be careful in recommending such products to those in the military.
Clinical studies on CBD revealed that CBD oil encourages hair growth by nourishing the scalp and strengthening the hair. CBD oil is packed with omega-3, omega-6 and omega-9 acids that help improve the scalp tissue’s quality. Fatty omega acids nourish the cuticles and moisture the hair. This soothes the dryness of the scalp as the scalp absorbs nutrients and promotes hair growth. CBD oil improves blood circulation in the area near hair follicles, encouraging their growth. CBD also helps to detox the hair from dust particles and harmful chemical deposits.
Other studies conclude that CBD has great anti-inflammatory properties. This is of use for soothing eczema and scalp inflammation. Ingredients in CBD oil regulate the functioning of the immune system, calm skin inflammation and decrease hair loss. This is helpful in the treatment of conditions such as folliculitis or psoriasis. CBD also reduces dandruff and dry scalp problems by influencing the scalp’s natural sebum and oil levels. Its antimicrobial properties reduce the risk of scalp infections.
IS CBD Cost-Effective?
CBD products are a viable solution for relieving the most common problems with scalp and hair care. But are they cost-effective? Let’s find out. The average price for a CBD hair and scalp care product ranges from $12 for a leave-in conditioner to $90 for a scalp and body oil. This is very cost-effective, especially when considering the fact that an ounce (30ml) of bottled CBD oil costs anywhere from $30 to $200. There are multiple CBD formulas available out there, and each one can be expensive to produce. Plus, the price of CBD can be greatly affected by formula potency, even if it is the same size as a less expensive bottle.
What Is Trending?
More consumers seek more natural cosmetic products. Due to its antioxidant and anti-inflammatory properties, CBD is one of the most powerful forces in the beauty industry. Recent development in the field of CBD research established two types of CBD products that can be applied to the human body—topical and transdermal. Topical CBD products are applied to the scalp. They only affect the top three layers of the skin, so CBD should not be absorbed into the bloodstream. Cannabinoids have demonstrated anti-inflammatory, antipruritic, anti-aging and anti-malignancy properties by various mechanisms including interacting with the newly-discovered endocannabinoid system of the skin, thereby providing a promising alternative to traditional treatments.
Market Size & Potential
The size of the CBD markets vary wildly. One projects a CAGR of 21.2% through 2028 to reach $13.4 billion, while another estimates sales will top $1.9 billion by 2026. Still, it seems everyone agrees that the category is growing 20-3% a year. The market is primarily driven by growing consumer awareness regarding the benefits of CBD-infused personal care products.
There is not enough space in this column to mention all of the CBD hair and scalp care products on the market. It was only a matter of time until CBD entered the hair care market. CBD is essential to the human endocannabinoid system—an entirely different human hormonal system. The endocannabinoid system (ECS) regulates multiple physiological processes, including cutaneous cell growth and differentiation. In dermatology, due to the combined lipostatic, antiproliferative and anti-inflammatory effects, CBD has potential as a therapeutic agent for the treatment of acne vulgaris. Research has also revealed that CBD reduces itching, and has anti-aging and anti-malignancy effects. As I emphasized in the “Skinification of Hair Care,” June 2021, the scalp is skin. Hair emerges from the scalp, and only a healthy scalp can grow healthy hair. This is true for CBD as well—it’s beneficial cutaneous effects extend to the scalp and hair.
