In most cases that begin with a small number of patches of hair<unk> , hair grows back after a few months to a year. In cases with a greater number of patches, hair can either grow back or progress to alopecia areata totalis or, in rare cases, alopecia areata universalis. No<unk>  of body function occurs, and the effects of alopecia areata are psychological <unk>  of self-image due to hair<unk> , although these can be severe.<unk>  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. Hair may grow back and then fall out again later. This may not indicate a recurrence of the condition, but rather a natural cycle of growth-and-shedding from a relatively synchronised start; such a pattern will fade over time. Episodes of alopecia areata before puberty predispose to chronic recurrence of the condition. Alopecia can be the cause of psychological stress. Because hair<unk>  can lead to significant changes in appearance, individuals with it may experience social phobia, anxiety, and depression.
