    TLDR A new skin model from hair follicles is a safer, simpler alternative for skin tests.
    The study established a new reconstructed human epidermis (RHE) model using keratinocytes derived from plucked hair follicles, offering a safer, simpler, and less invasive alternative to traditional skin-derived models. The hair follicle-derived RHE was found to be morphologically, genetically, and functionally similar to skin-derived RHE, making it a viable substitute for conventional models. This model was developed without the use of serum, fibroblasts, or biopsies, addressing the need for less invasive techniques in skin research. The study demonstrated that the hair follicle-derived RHE could effectively be used for skin irritation tests, showing comparable results to commercially available RHEs.

      community AGA responded to steroid shots? Biopsy wrong? Please help!

      in Female  2 upvotes 1 year ago
      A woman with AGA is using spironolactone, dutasteride, finasteride, oral minoxidil, bicalutamide, and anti-androgenic birth control but still experiences worsening hair loss. Steroid shots temporarily stop her hair shedding, leading her to question her biopsy results.

      community Please explain this Minoxidil phenomena

      The post discusses the difference in effects of Minoxidil (Min) on scalp and facial hair. The user questions why Min-induced hair growth on the scalp is temporary, while facial hair growth seems permanent, even after stopping Min. They propose theories, including different Min mechanisms on body and facial hair, the role of DHT, and the possibility of not achieving fully terminal hair. The responses include personal experiences and theories about Min's effects on hair growth.

      Minoxidil is not an anti-androgen; it is a growth stimulator and does not lower DHT like finasteride or dutasteride. Minoxidil can cause side effects like facial swelling and anxiety due to its vasodilator properties.
