    TLDR Low iron levels may be linked to hair loss in non-menopausal women.
    The study examined the link between body iron stores and diffuse non-scarring hair loss in non-menopausal women, involving 80 participants (40 with hair loss and 40 controls). It found a significant association between low iron stores (serum ferritin levels below 40 µg/L) and hair loss, with 57.5% of women with hair loss having low ferritin levels compared to 12.5% of controls. The study concluded that low iron stores were linked to diffuse hair loss, suggesting that screening and iron supplementation could be beneficial, although the effectiveness of supplementation was not determined. Anemia was also noted in many participants with low ferritin levels.

      In this conversation, 4990 discussed various treatments for hair loss, including oral minoxidil, PRP, transplan, Jak inhibitors, Dutasteride, Finasteride, Olumiant, Ketoconazole, RU58841, microneedling, baricitinib, and CCCA. They recommended scalp biopsies in unclear cases of DUPA, twice weekly to twice daily shampooing for topical minoxidil users, and two sessions spaced one month apart with follow up at month three to determine the effectiveness of PRP treatment.

      The efficacy of microneedling for hair regrowth as either a stand-alone therapy or adjunct to Minoxidil, and whether Tretinoin is a safer and more effective option. Replies include personal accounts from users who have had success with microneedling in combination with minoxidil and peptide serums, as well as considerations of technique, depth, and potential scarring.
