Spiral hair Spiral hair references Spiral hair Spiral or circle hairs are very tightly coiled with the coils one on top of another like a spring. The coils have a diameter of one to three millimeters and are frequently ingrowing hairs. They are found just beneath the skin and can be scratched out with a fingernail. The hair when it is pulled out springs back into its original shape.
Spiral hairs are a common phenomenon and are especially found in middle aged men.
In one survey 16 of 100 men were observed to have spiral hairs. They are most frequently found on the back, abdomen and thighs. They do not indicate any disease or treatable condition. Spiral hair references Levit F, Scott MJ Jr. Circle hairs. J Am Acad Dermatol.
