TLDR Stem cell exosome injections can safely improve hair growth and thickness in men with hair loss.

A study involving 8 male subjects with androgenetic alopecia (AGA) evaluated the safety and efficacy of intradermal injections of stem cell-derived exosomes over 24 weeks. The treatment, administered every 4 weeks, significantly improved hair density and diameter without serious adverse events. These findings suggest that stem cell exosome injections are a promising and safe treatment for promoting hair growth and thickening in male AGA patients, warranting further large-scale research to confirm long-term effects and mechanisms.

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 11 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
