Microneedling at depths greater than 0.6 mm may damage miniaturized hairfollicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.
Hairfollicles can potentially produce more hair strands with treatments like Minoxidil and finasteride. Notable improvements in hair density are possible, but achieving multiple strands per follicle is uncertain.
Hairfollicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.
Hairfollicles usually go dormant rather than die, and treatments like finasteride, minoxidil, and hormone therapy can sometimes reactivate them, though results vary. Complete regrowth is rare, especially in long-term bald areas, but some individuals see significant improvement with these treatments.
