Common causes of patchy hair loss are: alopecia areata (patches of baldness that usually grow back) traction alopecia (thinning from tight braids or ponytails) trichotillomania (the habit of twisting or pulling hair out) tinea capitis (fungal infection). The amount and patterns of baldness can vary greatly; it ranges from male and female pattern alopecia (androgenic alopecia, also called androgenetic alopecia or alopecia androgenetica), alopecia areata, which involves the loss of some of the hair from the head, and alopecia totalis, which involves the loss of all head hair, to the most extreme form, alopecia universalis, which involves the loss of all hair from the head and the body.

The problem of hair loss has resulted in many other myths and misconceptions. For instance, wearing hats does not “choke off” hair roots and promote baldness. Likewise, longer hair does not put a strain on roots.Once you think your hair is thinning, it’s worth a check to be sure. Even men who never lose much hair develop some receding at both temples during adolescence. Boys’ hairlines are straight across; adult men have more of an M shape.

Many conditioners, shampoos, vitamins, and other products, as well as procedures involving lasers and heat, claim to help hair grow in unspecified ways. These are harmless but useless and not worth the investment. To slow down hair loss, there are just two medically proven options:

Baldness generally involves hair loss on head where it often grows. There are different stages in hair loss it starts from hair thinning and this condition called androgenic alopecia or “male pattern baldness” that occurs in adult male humans and other species. The amount and patterns of baldness can vary greatly; it ranges from male and female pattern alopecia (androgenic alopecia, also called androgenetic alopecia or alopecia androgenetica), alopecia areata, which involves the loss of some of the hair from the head, and alopecia totalis, which involves the loss of all head hair, to the most extreme form, alopecia universalis, which involves the loss of all hair from the head and the body.

Alopecia can be treated in several ways but not all of them are successful. Some hair loss sufferers make use of clinically proven treatments such as finasteride and topically applied minoxidil (in solution) in an attempt to prevent further loss and re-grow hair. As a general rule, it is easier to maintain remaining hair than it is to re-grow; however, the treatments mentioned may prevent hair loss from Androgenetic alopecia, and there are new technologies in cosmetic transplant surgery and hair replacement systems that can be completely undetectable. There are durg-based treatments available that has been approved by the FDA.

There is one useful way to classify hair loss is by whether the loss is localized and patchy, or whether it affects large areas or the whole scalp.
