Hair Loss - Symptoms
Hair loss can occur as thinning, in which you may not notice hair falling out, or as shedding, in which clumps of hair fall out.
In the most common type of hair loss, inherited hair loss (androgenetic alopecia), men tend to lose hair on the front hairline and forehead and on top of the head. Eventually, only hair around the ears, the sides, and the back of the head remains. Women with this condition typically have gradual thinning throughout the scalp, but mostly on the top of the head.

Other causes of hair loss may also show distinct
patterns. For example, conditions such as
trichotillomania (compulsively pulling at the hair) or
alopecia areata (in which the immune system attacks
hair follicles ) result in obvious patches of hair loss, while stress and some
medicines result in clumps of hair falling out.
Because hair is an important part of appearance, hair loss can also result in loss of self-esteem and feeling unattractive, especially in women and teens.
