It can be caused by a diverse group of rare disorders that destroy the hair follicle , replace it with scar tissue , and cause permanent hair loss.
There is a risk of metastasis starting more than 10 years [citation needed] after diagnosable appearance of squamous-cell carcinoma, but the risk is low, [specify] though much [specify] higher than with basal-cell carcinoma. Squamous-cell cancers of the lip and ears have high rates of local recurrence and distant metastasis. [27]
Several hairs arise from the same hair follicle. Scarring and permanent hair loss may follow. The cause is unknown. Folliculitis keloidalis scarring on the nape of the neck is most common among males with curly hair. Oil folliculitis is inflammation of hair follicles due to exposure to various oils, and typically occurs on forearms or thighs.
Non scarring hair loss, also known as noncicatricial alopecia is the loss of hair without any scarring being present.

Alopecia totalis is the loss of all hair on the head and face.Its causes are unclear, but believed to be autoimmune.Research suggests there may be a genetic component linked to developing alopecia totalis; the presence of DRB1*0401 and DQB1*0301, both of which are human leukocyte antigens (HLA), were found to be associated with long-standing alopecia totalis.
