According to several studies and surveys on hair loss in American citizens showed that each year over $1.5 billion is spent by people for different hair growth therapies alone. The hair loss may also mean a very common problem of baldness.
Baldness has been divided into several various types. Each of them is caused by different factors. For example, the term ‘Alopecia’ is given to the condition where the person suffers from hair loss and becomes completely bald. Another type is ‘Alopecia Totalis’, referring to the loss of hair confined to the region of the individual’s scalp.
Another category is known as ‘Alopecia Universalis’. It means the total loss of hair from all over the body, including eyebrows and eyelashes.
Fourth category is ‘Alopecia Areata’. It is the condition where an person suffers from sudden loss of hair in the form of patches. The Androgenetica Alopecia is another category, commonly found men, in comparison with their female counterparts. As the name suggests, it is a genetic problem. It is caused by a set of male sex hormones - the androgens, hence the name androgenetica alopecia.
Other forms of baldness include such conditions as: ‘Involutional Alopecia’ in which a person suffers from gradual loss of hair corresponding with his/her age. ‘Telegen effluvium’ where hair is gradually shed, more frequently as a result of side effects from the use of certain drugs, as well as conditions such as weight loss, anemia, stress, and pregnancy.
