    GlossaryHair Bulb

    rounded base of the hair follicle where growth starts

    The hair bulb is the rounded, bulbous structure at the base of the hair follicle, located in the dermis layer of the skin. It is the site where hair growth begins, containing actively dividing cells that produce the hair shaft and the inner root sheath. The hair bulb also houses the dermal papilla, which supplies nutrients and signals necessary for hair growth.

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

      in Research/Science  110 upvotes 11 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.

      Sodium dodecyl sulfate, oleic acid, and palmitoleic acid may promote hair growth, but their safety and effectiveness for humans are uncertain. Users consider trying these treatments cautiously, exploring alternatives like ostrich oil and microneedling.

      community A Theory on Why Microneedling Works

       170 upvotes 6 years ago
      Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.
