After combing the hair backward, I saw that she's got some brownish crusting on top of the spot.
I tried to gently dislodge the crusting to see what is at the source.
In early childhood it is called infantile eczema and is characterized by redness, oozing, and crusting.
Side effects include bruising, skin discoloration, swelling, crusting, and minor bleeding.
Sometimes inflamed and filled with pus, scalp ringworm lesions can cause crusting, flaking, and round bald patches.
The picture left shows a large area of discoid eczema on the lower leg, note the crusting.
This would be fairly normal, unless the eyes are crusting over and you can detect a foul smell from the area.
