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