Ceramic Flat Irons: Improper Use Leading to Acquired Trichorrhexis Nodosa

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.
