Hair loss, also referred to as alopecia, can be caused by different factors. Modern science finds few reasons to be most common, but the studies are still ongoing, and sometimes it is very difficult to determine what exactly causes the hair loss in this or that particular individual.


The timing in which the hair loss occurs can provide very important clues as to the cause of this condition. For example, fast and sudden hair loss will indicate that it was caused by some disease, and this needs to be addressed with a health care professional right away. Slow and gradual hair loss may indicate that it is caused by heredity or aging and other factors.


The first and very common type of alopecia is male balding. Scientists suggest that male balding in most cases is caused by genetics and inherited from the parents. It starts occurring in men before or right after 30 and progresses gradually. Scientists also suggest that one more possible causes of hair loss have to do with male hormones. It is interesting to know that the male hormones are generated by both males and females but are produced at higher levels in males. Discovery Health provides more information on this subject. Due to the chemical reaction occurring in the body, male hormone testosterone gets converted to Di  Hydro Testosterone, which is the primary cause of the hair loss, because Di Hydro Testosterone is responsible for hair root destruction.


Mayo Clinic suggests that hormonal changes in women occurring during pregnancy, childbirth, discontinuation of birth control pills or approaching menopause can also be a trigger for hair loss. Mayo Clinic website also provides supportive facts on hair loss causes and useful information on hair growth cycles, risk factors and treatment options for hair loss.


Some of modern scientists also offer one more possible explanation for hair loss - evolution. According to Beat Psoriasis website it was suggested that baldness evolved in males through sexual selection as the sign of aging and maturity and helped them to survive adaptation. Two researchers in this field, doctors Muscarella and Cunningham, offered this theory describing how evolution could possibly lead to balding in modern men.


Sudden hair loss in both men and women suggests that some kind of disease or condition or drugs could be a possible cause. Those conditions include anemia, infections, anorexia, thyroid diseases or ringworm. There is a suggested connection between diabetes and hair loss as well. Because of high levels of blood sugar, the necessary nutrients and oxygen are not able to reach the hair follicles, which leads to hair loss. Diabetes can also trigger hormonal imbalance, which in turn leads to hair loss. For more information about diabetes and hair loss, search for Diabetes and Hair Loss.


Hair care habits can also cause hair loss. Some of them can include brushing hair while it is wet, using too much shampoo, which dries the scalp, high heat from blowdries, and some chemicals used during hair coloring, or even hair accessories.

It is possible that stress and nutrition also can be responsible for hair loss, but those theories are still not confirmed.


Overall, there are many treatment options offered for those suffering from hair loss. The first step in finding the right treatment is determining the right cause of this condition.
