    TLDR Chegu goats have two types of hair follicles, with primary ones having glands and muscles, and secondary ones lacking them.
    The study examined the skin and hair follicles of seven healthy Chegu goats, revealing that skin thickness ranged from 2.2 to 3.5 mm, with an average of 2.84 mm. The epidermis thickness varied from 12 to 26 μm, averaging 21.47 μm. The dermis was composed of dense irregular connective tissue with collagen fibers. Hair follicles were accompanied by sebaceous glands, sweat glands, and arrector pili muscles, with sweat glands opening into the follicle neck above the sebaceous gland. Two types of hair follicles were identified: primary follicles, which were associated with glands and muscles, and secondary follicles, which lacked these structures. The average follicle density was 30.66 follicles/mm, with a secondary to primary follicle ratio of 18.9.

      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.

      The post discusses the theory that persistent dandruff in areas prone to hair loss could be a sign of hair follicles dying due to DHT, indicating balding. The responses vary, with some users noting improvements in dandruff and hair loss with treatments like Dutasteride, while others experienced hair loss without dandruff.

      community Are Derma Rollers Actually Harmful in the Long Run?

      in Microneedling  40 upvotes 9 months ago
      Derma rollers may cause scarring alopecia, leading some to prefer dermastamps or dermapens for microneedling. Combining minoxidil with microneedling is effective, but proper technique and healing time are essential to prevent damage.
