CBD for hair and the scalp: what can be expected
Par The Phytogrammes team ·
CBD cannot legally claim any anti-hair-loss effect for a hair cosmetic sold in France, since cosmetic regulation prohibits that type of claim (source: cosmetic regulation). The endocannabinoid system does, however, take part in the regulation of sebum, including at the level of the scalp (source: dermatology/ECS), which explains the interest of certain formulations for unbalanced scalps.

What is the link between the endocannabinoid system and the scalp?
The endocannabinoid system (ECS) is present in the skin, including at the level of the scalp, where it takes part in the regulation of the sebum produced by the sebaceous glands (source: dermatology/ECS). A scalp that is too oily or, conversely, too dry often reflects an imbalance in that production.
It is this mechanism that explains why certain hair cosmetics include CBD in their formulation, in the hope of supporting an unbalanced scalp, without that constituting a promise of guaranteed results.
What can hemp oil bring to a hair product?
Hemp seed oil, often combined with CBD in hair cosmetics, is rich in omega-3 and omega-6 fatty acids (source: cosmetic compositions). These essential fatty acids are commonly used in cosmetics for their nourishing properties and their role in maintaining the skin barrier.
It is important to distinguish hemp seed oil, which contains no significant quantity of cannabinoids, from CBD-rich hemp extracts. The two ingredients often coexist in the same formula, each bringing different cosmetic benefits.
Can CBD slow hair loss?
No. No anti-hair-loss claim is authorised for a CBD cosmetic in France (source: cosmetic regulation). Hair loss stems from complex mechanisms, often hormonal or genetic, which go well beyond the field of action of a cosmetic product applied locally.
A product that promises to « stop hair loss » thanks to CBD does not comply with the regulatory framework in force. For any unusual or marked hair loss, consulting a dermatologist remains the appropriate step; CBD does not replace medical advice.
How can a CBD product be built into a hair routine?
A CBD shampoo, serum or hair oil is used like any other targeted cosmetic product, alongside a routine suited to your scalp type. Users who report an increased feeling of comfort do so on an individual basis, without that constituting proof of efficacy that can be generalised.
As with CBD products applied to facial skin, regularity of application often counts for more than the quantity used in one go, a principle already observed for CBD use on oily skin (see our article on CBD and acne).
Frequently asked questions
Can CBD regulate an oily scalp?
The endocannabinoid system takes part in the regulation of sebum, including on the scalp (source: dermatology/ECS). That is not equivalent to a promise of validated clinical efficacy for every user.
Are hemp oil and CBD the same thing?
No, hemp seed oil is rich in omega-3 and omega-6 but contains very few cannabinoids (source: cosmetic compositions). CBD is a distinct extract, drawn from other parts of the plant.
Can a CBD shampoo prevent hair loss?
No, no anti-hair-loss claim is authorised for this type of cosmetic in France (source: cosmetic regulation). A product that states otherwise does not comply with the legal framework.
What should be done in the event of significant hair loss?
Consulting a dermatologist is recommended, since this situation often stems from medical or hormonal causes. CBD does not replace medical advice in that context.
