MCL-1 is important for hair follicle stem cell survival, but its impact on human hair regrowth is unclear. Minoxidil and finasteride are the main treatments, with doubts about new discoveries leading to effective human solutions soon.

Microneedling should target depths of 0.5mm to 1.5mm for hair loss, with weekly sessions at 1mm recommended. Combining microneedling with Minoxidil is common for improved results.

PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hair follicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.

Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.

Tazarotene shows potential as a standalone treatment for hair regrowth by stimulating new hair follicle formation and promoting angiogenesis, similar to microneedling effects. It can be used topically without minoxidil, but users should start with a low concentration to avoid irritation.

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.
