No loss of body function occurs, and the effects of alopecia areata are psychological (loss of self-image due to hair loss), although these can be severe. Loss of hair also means the scalp burns more easily in the sun. Patients may also have aberrant nail formation because keratin forms both hair and nails. [citation needed]
Hair loss, also known as alopecia or baldness, refers to a loss of hair from part of the head or body. [2] Typically at least the head is involved.

Dutasteride is also used in the treatment of male pattern hair loss and appears to have better effectiveness than finasteride for the condition. [27] [28] [29] While used off-label for male pattern hair loss in most of the world, dutasteride is specifically approved for this indication in South Korea and Japan. [30] [31]
Non scarring hair loss, also known as noncicatricial alopecia is the loss of hair without any scarring being present. [1] There is typically little inflammation and irritation, but hair loss is significant. This is in contrast to scarring hair loss during which hair follicles are replaced with scar tissue as a result of inflammation.
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.
Ophiasis [1] is a form of alopecia areata characterized by the loss of hair in the shape of a wave at the circumference of the head. [2] It gets its name from Greek ὄφις ophis 'snake' because of the apparent similarity to a snake-shape and the pattern of hair loss. [3] The term "sisaipho" is used to characterize the inverse pattern.
