Ceramic Flat Irons: Improper Use Leading to Acquired Trichorrhexis Nodosa

    Paradi Mirmirani
    TLDR Improper use of ceramic flat irons can cause severe hair damage.
    The document discussed the improper use of ceramic flat irons, which led to acquired trichorrhexis nodosa, a condition where hair becomes fragile and easily broken. Although ceramic flat irons were marketed as safer due to more even heat distribution, they still caused significant hair damage when used improperly. The damage was often due to high temperatures and frequent use, especially on chemically treated or damp hair. The study highlighted that hair breakage could occur in up to 18% of African American women using hot combs, and similar risks applied to ceramic flat irons. Dermatologists were advised to inquire about flat iron use when assessing hair loss, and patients were counseled to avoid heat and chemicals, cut damaged hair, and practice gentle hair care for recovery, which could take 2 or more years.

      Disinfecting microneedlers is important to prevent infection, with suggestions to use high-percentage alcohol or denture tablets for sterilization. Rollers may cause skin damage, so stamps or pens are recommended for safer microneedling.

      community New molecule PP405 vs exercise

      in Research/Science  38 upvotes 9 months ago
      PP405 targets hair follicle stem cells differently than exercise-induced lactate, suggesting exercise alone may not replicate its benefits. Minoxidil and finasteride are recommended alongside exercise for hair regrowth, with additional suggestions like spicy food and infrared exposure.

      Significant hair regrowth was achieved using 0.5mg oral finasteride, a topical mix of finasteride and minoxidil, and dermastamping. Initial side effects like achy testicles were managed by adjusting the regimen.
