    TLDR Heat and chemicals improve finasteride delivery to scalp and hair follicles, potentially enhancing treatment for hair loss.
    The study investigated the use of heat and chemical penetration enhancers to improve the delivery of finasteride to human scalp skin and hair follicles. The results showed that short durations of externally applied heat significantly increased finasteride penetration into human scalp skin after 24 hours. The use of short durations of heat in combination with specific chemical penetration enhancers was able to increase the delivery of finasteride to human scalp skin and provide focused drug delivery to the hair follicles. The study suggests that this approach could be used to enhance the efficacy of topical finasteride for the treatment of androgenetic alopecia.
