Hair

About half of individuals with IP have minor abnormalities of their hair, usually a loss or lack of hair (alopecia) on the crown of the head. The alopecia is probably caused by scarring from the rash, but this is not proven. As with other children, sparseness of hair as a child does not correlate with the quantity of hair as an adult. Hair color is normal, but the hair may be coarse, wiry, and "lusterless". For the most part, individuals do not have substantial problems with their hair.
