The Biology and Genomics of Human Hair Follicles: A Focus on Androgenetic Alopecia

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

PP405 shows promise in regenerating hair by activating dormant follicles. Other treatments like VDPHL01 and Breezula are also advancing, providing new hope for hair loss solutions.

Beard gains from minoxidil are usually permanent due to facial hair follicles' lower sensitivity to DHT. Scalp hair requires ongoing DHT suppression with treatments like finasteride, dutasteride, and RU58841 to maintain gains after stopping minoxidil.

Minoxidil alone is often insufficient for treating hair loss because it doesn't address the DHT-related cause. Combining it with finasteride, a DHT blocker, is generally more effective.
