Characterising Neurotransmitter Signalling in Human Skin and Hair Follicles

Stress can lead to hair loss by affecting hair-follicle stem cells, and this loss is harder to recover from if one has male pattern baldness (MPB). Treatments like finasteride and minoxidil are used to address hair loss, but stress-related hair loss differs from androgenic alopecia.

Hair follicles cannot be desensitized to DHT like allergies; treatments focus on reducing DHT levels or blocking its effects using methods like finasteride, GT20029, or PROTACs. Topical treatments like ceterizine and BPA application are also mentioned.

The conversation discusses whether to use finasteride for hair loss, considering its role in inhibiting DHT and 5AR, which can affect brain function and mood. Some users report anxiety and depression from finasteride, while others do not experience these side effects and emphasize the importance of DHT for brain and prostate health.

Topical melatonin was found to significantly increase hair density and decrease scalp conditions like seborrheic dermatitis. The user is considering using it alongside finasteride and oral minoxidil for treating hair loss and scalp health.

The user experiences histamine intolerance with alcohol-based hair loss treatments like Rogaine foam and seeks alternatives. Suggestions include alcohol-free and PPG-free topical minoxidil or finasteride, and trying Spectral products with different solvents.

Quercetin reduced scalp soreness and may help with histamine-related hair loss. The soreness felt like inflamed follicles beneath the scalp surface.
