Trichorrhexis nodosa - Symptom

Symptoms:

Your hair may appear patchy or like it's not growing.

In African-Americans, looking at the scalp area using a microscope shows that the hair breaks off at the scalp area before it grows long.

In Caucasians, the problem often appears at the end of a hair shaft in the form of split ends, thinning hair, and hair tips that look white.

Signs and tests:

Examination of the hair shafts with a microscope may reveal changes that indicate trichorrhexis nodosa.
