What are the most common causes for hair loss?
Unless the result of a temporary illness or treatment, male hair loss is caused by sensitivity on areas of the scalp to the male sex hormone called DHT (dihydrotestosterone). This form of testosterone causes the hair follicles on the scalp to shrink until they become so small that they can no longer replace any lost hairs or be a healthy environment from which individual hairs can grow.
Rarer forms of hair loss, like alopecia areata (spot baldness), are auto-immune diseases which cause hair to be lost in patches across the scalp and can develop into total scalp (alopecia totalis) or total bodily (alopecia epidermis) baldness in around 1-2% of cases.
In most cases, male hair loss doesn’t pose any health risk or indicate a present medical problem. However, for some men, hair loss can be the cause of much emotional distress, be damaging to their self-esteem or even lead to depression. It is important to remember that most if not all men and some women will experience hair loss at some point in their lives.
