    TLDR Hair problems can be caused by genetics or the environment, and treatment should focus on the cause and reducing hair damage.
    Hair shaft abnormalities, which can be congenital or acquired, manifest as changes in the hair's color, density, length, and structure, often leading to brittle and unmanageable hair that appears dry and lacks luster. These conditions can be localized or generalized and may be due to genetic factors or external influences. Diagnosing hair shaft diseases involves optic and polarized light microscopy, along with a thorough patient history and physical examination that includes other skin appendages. Understanding hair biology and embryology is crucial for identifying the various syndromes associated with hair shaft abnormalities. Treatment should address the underlying cause and minimize hair damage from external factors, with a recommendation for shorter hairstyles to ease management for affected individuals.

      Microneedling is unlikely to damage existing hair if done with a device using a smaller needle count, like a 9-needle cartridge, and a stamping motion. Hair follicles are deeper than the typical needle penetration depth.

      in Research/Science  10 upvotes 1 month ago
      Caffeine in hair care can support hair growth but is not a standalone solution; it's best used in combination with other treatments like minoxidil and finasteride. Some products combine caffeine with these treatments for enhanced effects.
