Although in males, Alopecia Androgenetic if left untreated can result in complete all-over baldness, it very rarely has the same effect in women.

Alopecia Areata
Alopecia Areata is a hair loss condition that creates one or more bald patches, usually round in shape, on the scalp and occasionally on the body. These patches are quick to develop and are usually cause by an auto-immune disease which treats normal parts of your anatomy as foreign bodies. This disease effects both men and women and is not to be confused with male or female pattern balding as its path is less targeted. Alopecia Areata has multiple different ways it can develop, in many cases the hair grows back like normal although temporary hair discolouration can occur. It can also merge together to form larger areas of baldness and other areas of hair can start losing hair such as the eyelashes or beard.

Propecia is a treatment for hair loss which comes in 1mg pill form. The chemicals in the pill lowers the levels of hormones that are designed to shed hair from the scalp causing baldness. This treatment has been debated a lot as, although trials have shown that more than half the people that where treated with this drug showed hair growth after approximatly 6 months, it is required that the treatment is kept up constantly (one pill every day) or the scalp will return to its original state. Thus it is a very temporary treatment.
