Researchers at the University of Virginia discovered a new group of stem cells in hair follicles that could potentially restore hair growth. The findings suggest that activating these stem cells might offer a new way to combat hair loss, though practical treatments are still years away.
Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.
Sunburns on the scalp can cause permanent hair loss, especially for those using Tretinoin or Tacrolimus. Wearing UPF 50+ hats is recommended to protect against UV radiation.
A user has been using minoxidil, finasteride, derma stamping, and keto shampoo for hair loss for 5 months, noticing baby hairs but no thickening. Another user suggests trying topical magnesium chloride with UV light as an additional treatment.
Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
