    GlossaryTerminal Hair Follicles

    structures producing thick, pigmented hair on scalp and body

    Terminal hair follicles are the structures in the skin that produce terminal hair, which is the thick, pigmented hair found on the scalp, face, armpits, and pubic area. Unlike vellus hair, which is fine and light, terminal hair is coarser and darker, and its growth is influenced by hormonal changes, particularly androgens.

      community Microneedling and miniaturized hair follicles depth

      in Microneedling  7 upvotes 3 days ago
      Microneedling at depths greater than 0.6 mm may damage miniaturized hair follicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.

      community How true is the statement: dead follicles don't grow back?

      in Research/Science  107 upvotes 2 months ago
      Hair follicles 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.

      community Why don't Minoxidil regenerated hairs become terminal on the head?

      in Minoxidil  101 upvotes 1 month ago
      Minoxidil helps hair growth by increasing blood flow and prolonging the growth phase, but it doesn't address the root cause of hair loss, such as DHT sensitivity. Finasteride can help maintain some gains by blocking DHT, but stopping Minoxidil often leads to hair loss because the new hairs are dependent on it.
