Permanent Hair Dyes and Bladder Cancer Risk

Rotenone, a natural plant extract, may promote hair growth by increasing LDH activity and blocking MPC in the scalp, but it carries risks due to its toxicity. The suggested formulation includes Barbasco extract, DMSO, propylene glycol or PEG-400, ethanol, and a carrier oil.

Oral supplementation of Nicotinamide Mononucleotide (NMN) improves hair quality and appearance in middle-aged women. However, it may reduce total hair density, possibly due to seasonal shedding.

TDM-105795 showed promising hair growth results, with higher efficacy than placebo and minimal side effects. It activates dormant hair follicle stem cells and may maintain gains without immediate loss, unlike minoxidil.

Hair loss treatments discussed include microneedling, minoxidil, tretinoin, finasteride, dutasteride, pumpkin seeds, saw palmetto, and scalp massage. The consensus is that finasteride or dutasteride is necessary for significant regrowth, while other methods may only slow hair loss.

Topical 2-deoxy-D-ribose (2dDR) regrows hair in mice almost as well as 2% Minoxidil. However, 2dDR may contribute to oxidative stress and hair loss due to the formation of advanced glycation end products (AGEs).

GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.
