Using MALDI-MSI Analysis to Study Distribution of FOL-005, a Potent, Novel Inhibitor of Human Hair Growth, After Subcutaneous Injection in Mice

Minoxidil, finasteride, and RU58841 are discussed as treatments for hair loss, with excitement around a new drug, PP405, and a reformulated oral minoxidil in trials. Concerns about cost, side effects, and long-term use are also mentioned.

PP405, a topical treatment, shows promise for hair growth by activating inactive follicles, with 66% of participants experiencing positive results. The treatment is well-tolerated and may proceed directly to Phase 3 trials, offering a potential alternative to minoxidil and finasteride.

Minoxidil was applied to a single miniaturized hair follicle over four months, resulting in less miniaturization but not yet terminal growth. The user used a 5% minoxidil solution, specifically the Regaine brand, and observed changes using a handheld WiFi microscope.

Significant hair regrowth was achieved using a topical combination of 0.3% finasteride and 6% minoxidil, with weekly dermastamping and ketoconazole shampoo, without side effects. Others suggested additional treatments like red light therapy and PRP.

A 26-year-old is using 5% minoxidil twice daily and 1 mg finasteride every other day, along with biotin and collagen supplements, for hair regrowth. They apply minoxidil to the temples and crown and experienced initial shedding in the first month.

PP405 shows significantly better early-stage hair regrowth results compared to minoxidil and finasteride, with 31% of users experiencing over 20% density increase in 4–8 weeks. Minoxidil and finasteride show minimal or no visible regrowth in the same timeframe.
