research The Phytocannabinoid (–)-Cannabidiol Operates as a Complex, Differential Modulator of Human Hair Growth: Anti-Inflammatory Submicromolar versus Hair Growth Inhibitory Micromolar Effects
This exploratory study found that cannabidiol (CBD) at higher concentrations may inhibit hair growth by promoting the onset of catagen in human hair follicles, while lower concentrations showed potential anti-inflammatory effects without promoting catagen.
