caffeine hair follicles antioxidants hair retention shampoo formulation

TLDR The new shampoo effectively delivers caffeine to hair follicles to help keep hair, especially as people age.

The study "Follicular Delivery of Caffeine from a Shampoo for Hair Retention" tested a new shampoo formulation on 9 male participants to measure its effectiveness in delivering caffeine to hair follicles. The results showed that 8-9% of the caffeine absorbed into the skin was recovered in the hair follicles, matching the performance of an existing caffeine-based shampoo. The study concluded that this new shampoo formulation effectively delivers beneficial antioxidants, including caffeine, to improve hair retention, especially useful in retaining hair during aging.
