What has caused gray hairs to appear on my 15-month-old's head?
A few gray hairs are generally nothing to worry about. If the changes are progressive, or if she has any other health problems, it's worth discussing with your daughter's pediatrician. Occasionally, premature graying of hair can be a sign of anemia, thyroid disease, and, very rarely, some genetic disorders. The most common cause is a skin disorder called vitiligo, whereby skin pigment is lost and white patches appear scattered on the skin surface. If vitiligo occurs in the scalp, gray hairs may be seen overlying that area. This disorder is fairly unusual at such a young age, though. Keep an eye on things, and if the changes are progressing, have her evaluated.
