Hair loss, scientifically known as alopecia, can be triggered by a number of different conditions, some of which can be prevented, whereas others cannot. Permanent hair loss, while physically nonrestrictive, can cause severe psychological problems, as the loss of hair can be a burden on anyone's self-image in any society. Knowing the potential causes of permanent hair loss can help you prepare yourself if you suspect it could happen to you.
Genetics
You can't do anything to change your genes, and unfortunately, your genes could be the reason that you are losing, or will eventually begin to lose, your hair. Androgenetic alopecia is one of the most common forms of hair loss and is often referred to as male pattern baldness, although it can also occur in women. Androgenetic alopecia can begin as early as puberty and is characterized by an m-shaped thinning of the hair, leaving a sloping peak in the middle, but sparing the sides and back. According to the American Association of Family Physicians, excess androgen hormones alters the growth and shape of your hair, creating the pattern.
Lupus
Some diseases can cause hair loss, and while your hair will usually grow back after the disease has been cured, some diseases cause permanent hair loss. Lupus erythematosus is an autoimmune disease that causes your body to attack its own skin cells. These outbreaks can cause inflammation of the skin, rashes and scarring on the scalp. The scarring damages the scalp and results in the hair follicles' inability to grow, causing permanent hair loss. The causes of lupus erythematosus isn't clear, but viruses, ultraviolet light and your genetics may play a role.
Lichen Planus
Similar to lupus erythematosus, lichen planus is another autoimmune skin disease in which your body begins to attack itself. Lichen planus can affect your body in a number of different ways, creating dry and sometimes painful patches all over your skin as well as in the mucus membranes such as the mouth or genitals. This autoimmune attack can also occur on your scalp, creating scar tissue and preventing the formation of healthy hair follicles, resulting in permanent hair loss.
