Male pattern baldness is the common type of hair loss that develops in most men at some stage. The condition is sometimes called androgenetic alopecia. Hair loss can occur at the front, top and crown of the head. An advanced classification system known as the Norwood Hamilton Scale is most often used to identify a level of hair loss.
There is no way of predicting if you will suffer hair loss or to what degree you’ll end up but those who begin losing their hair in the late teens or early twenties have the highest chances of progressing to a high Norwood Scale. Baldness is determined by genetics from both or either parents.
Hair loss is caused by the hormone receptors in your hair roots. The receptors attract the male hormone Dihhydroestosterone (DHT) triggering the hair loss process.
Usually at first the hair begins to thin (recede) at the sides (temples). At the same time, the hair usually becomes thin on the top of the head. A bald patch gradually develops in the middle of the scalp. The receding sides and the bald patch on the top (the crown) gradually enlarge and join together, leaving a patch at the front. The patch at the front eventually thins as well.
