Baldness that is genetically determined is rare, and often irreversible. Baldness, at least amongst men, is becoming a macho look, and treatments that work or help or prevent are becoming much more abundant. Baldness is defined as an area of the scalp that is no longer covered by hair.

Balding may be caused by genetic disorders such as androgenetic alopecia, alopecia areata and so on. It can also be caused by hormonal imbalances, chemotherapy and some medications.

Telogen effluvium is a temporary kind of hair loss. Hair falls out suddenly in handfuls. It may occur because of a physical or emotional shock or trauma.

An active intellect or mental illness can cause baldness. Because of the close proximity between the brain and hair, it was believed that too much brain activity or too many psychological problems could contribute to hair loss. Needless to say there is no validity to this theory and plenty of examples to refute it.

Hair is made in hair follicles which are like tiny pouches just under the skin surface. Some men have areas on the scalp that are extremely sensitive to the male sex hormones that circulate in men's blood. The hormones make the hair follicles shrink from where the hair grows. After a while, they become so small that they can't replace lost hairs.

The main reason for hair loss in most of the men is the hormone called DHT and this hormone is fed by the sebum gland that is inside the scalp in the hair follicle. A very specific enzyme called 5 alpha reductase converts testosterone to DHT (the hormone for hair loss). This bad enzyme feeds off the cholesterol in the sebum or scalp oils.

A number of things can cause excessive hair loss. For example, about 3 or 4 months after an illness or a major surgery, you may suddenly lose a large amount of hair. This hair loss is related to the stress of the illness and is temporary.
