Caffeine 1% Hair Growth Serum - 4 oz (120 mL)
Caffeine and Hair Growth
Recently, certain newer advances have shown caffeine to have beneficial effects in patients suffering from androgenic alopecia (AGA). The proposed mechanism which would counteract DHT-induced miniaturization of the hair follicle include inhibition of phosphodiesterase by caffeine, which increases cAMP levels in cells and therefore promotes proliferation by stimulating cell metabolism.
A study conducted by Fischer et al. used hair organ culture model to investigate the effects of testosterone and caffeine on hair follicle growth stimulation. This in vitro study used scalp biopsy samples from male AGA patients which were cultivated using different concentrations of testosterone and/or caffeine for a period of 120-192 hours. Addition of caffeine in concentrations of 0.001% and 0.005% were found to counteract the suppressive effects of testosterone on hair growth, with a higher hair shaft elongation seen at 120 h after caffeine administration, compared to control group. This in vitro study thus clearly demonstrates that caffeine is a stimulator of human hair growth which may have importance in the treatment of AGA.
A recent study which assessed the follicular penetration of topical caffeine in hair follicles proved hair follicles to be faster route of drug delivery for topically applied drugs. An important requirement for the treatment of AGA is follicular drug delivery.
A recent study assessed the follicular penetration of caffeine on topical application in a shampoo formulation for 2 min and showed that penetration via hair follicles was faster and higher compared with the interfollicular route and that hair follicles were the only pathway for faster caffeine absorption during the first 20 min after application.
The beneficial effects of topical application of caffeine in AGA can thus be attributed to inhibition of phosphodiesterase, improvement in barrier function, follicular penetration, stimulation and promotion of hair growth. Thus it appears to be a useful adjuvant in the management of AGA.

Brandner et al. proved by their double-blind placebo-controlled trial that caffeine application causes a substantial reduction in the transepidermal water loss in men compared to women, thus improving barrier function in men. Regarding the route of delivery of caffeine, hair follicles are considered an important route for drug delivery.
