What constitutes a normal appearing scalp?

Recognizing the Normal Scalp

In order to appreciate what is “abnormal” on the human scalp, one needs to fully understand what is normal and what are all the variations of normal that are possible.

The normal scalp is not red and not flaky. Hairs emerge in groups of 1,2 and 3 hairs. In some cases (especially younger individuals) hairs come out occassionally in groups of 4 hairs too. Most hair follicles in an area are the same diameter (caliber) but a bit of variation is normal and acceptable. The finding of an occassional thin hair carries no significance and does not mean the individual has androgenetic alopecia.
