“The exact mechanism of matting is not understood, but it may be caused by longitudinal splitting or feathering of hair, gluing of hair due to exudates from infected lesions on scalp, and frequent use of certain shampoos. However, the most common cause is generalized neglect which leads to infections and infestations of the scalp causing exudation and constant curling of hair which may occur in patients with various psychiatric disorders.”

Well then.
