- There are nine types of hair loss, or alopecia, relating to the way in which hair is lost. Alopecia barbae, for instance, causes hair loss on the face. Another type, alopecia universalis, involves hair loss over the whole body. The most well-known form of hair loss in men is male pattern baldness.
- Hair loss is common, affecting as many as 2 million men in America.
- Hair loss in men can occur at any time, sometimes because of illnesses or surgery. However, most cases appear in middle-aged or elderly men. Cases in teenagers are rare but do occur.
- Hair loss is often genetic. As much as 25 percent of men who experience hair loss have a family history of a similar problem. Men who produce too much testosterone produce less estrogen, which is necessary for healthy hair follicles and hair growth. Medical conditions or procedures can bring on hair loss as well--chemotherapy drugs, for instance, almost always cause hair loss. Diet may also play a role, as B vitamins and other minerals are related to the production of healthy cells and proteins. Lastly, some forms of hair loss in men may be related to the immune system. It is theorized that the immune system overreacts and attacks the cells that are within the follicles responsible for hair growth.
- In men, typical hair loss begins on the back of the scalp, with the bald spot growing larger over time, or the hair line recedes from the forehead. In women, it is more common for hair loss to occur as a general thinning of the hair. Women typically can hide their hair loss more easily than men by letting their hair grow longer or by styling the remaining hair to conceal thin areas or give the appearance of body.
- Treatments for hair loss include medicine, hormone therapy, dietary changes and follicular transplant. Those with hair loss should consult with a professional to see which hair treatment is best for them.
