This is a rare dermatological disorder with very little research and about 3 case studies. There is a case in the US of a young adult female 33 year old female with this disorder of hair imbedded in the skin that migrates in long strands into the scalp, eyebrows, extremities, torso, just about everywhere on the body. Exfoliation can be performed by massaging; hair loss occurs when exfoliation is performed. For example, loss of eyebrow hair and hair at temples.
Other marked signs are linear indentations at a site of migration, or a raised red line, irregular patches of "goose bumps".
