Permeation of Topically Applied Caffeine Through Human Skin – A Comparison of In Vivo and In Vitro Data

A user is creating a home topical solution for hair loss using zinc, essential oils, and caffeine, aiming for a 0.001% caffeine concentration. They also use topical finasteride and are considering other treatments like low-level laser therapy, while discussing the effectiveness of various hair loss treatments with others.

Topical caffeine is suggested as a beneficial adjunct treatment for hair growth due to its anti-fibrotic, anti-inflammatory, antioxidant, and other properties. There is skepticism about its effectiveness, especially at low concentrations like in Alpecin liquid.

Caffeine's effectiveness in reversing hair loss is debated, with some users skeptical about caffeine-based products like Alpecin. Alternatives like Nizoral are suggested, but results vary, and some experience side effects from treatments that lower DHT.

Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.

A user discusses using Alpecin Caffeine Liquid for scalp health and considers dissolving finasteride tablets into it for a DIY topical treatment. They inquire about potential absorption issues with this method.

PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.
