Scalp Itching

Scalp itching (Scalp pruritus)

Every new patient I see gets asked about scalp itching. It's a very useful question because it leads me down a pathway of additional questions to figure out if I need to be concerned. In addition to scalp itching, I usually ask about scalp burning and scalp pain.

There are a very large number of causes of scalp itching, sometimes referred to as scalp "pruritus". Most of the time, the causes of scalp itching are not associated with hair loss but rather a coincidence. However, one needs to quickly work through a series of questions to get to the final answer and the confident declaration - "You're scalp itching is nothing to worry about"

Of course, my list doesn't stop there, just this blog. If one has scalp itching, a careful examination of the scalp is needed and a series of fairly detailed questions.
