Trichorrhexis nodosa

Trichorrhexis nodosa.

History

         A 5-year old girl presented with sparse, short and easily-broken scalp hairs. The mother noticed the hair defect since early months of life. The skin, nails, teeth and mentality were normal. There was no family history of similar hair problem. Many hairs were plucked, mounted on a microscopic slide and carefully examined under the light microscope. Hair shaft fractures were seen with the hair ends at the fracture line look like two brooms stuck together.
