Cutis verticis gyrata describes a scalp condition with convoluted folds and deep furrows that resemble the surface of the brain. Cutis verticis gyrata is a progressive condition. It is mainly troublesome due to the cosmetic appearance. Rarely, it can be complicated by malignant melanoma developing within a melanocytic naevus. Cutis verticis gyrata occurs more commonly in males. The primary form of cutis verticis gyrata has a reported male-to-female ratio of 5:1. The incidence of cutis verticis gyrata may be reported as lower in women because longer hair may camouflage the condition (Ref: Dermnet NZ).
This is a cosmetic issue for those who have it. As you can see in this photo, styling the hair can be a problem.
