Causes of Excessive Hair Loss

What is causing your of excessive hair loss?

Many things can cause excessive hair loss. An example, about three or four months after an illness or major surgery you might lose a a fair amount of hair. Hair loss like this is related to stress of  illness and is only temporary.
Hormonal is another cause of hair loss. If your thyroid gland is overactive or underactive, your hair may fall out. This hair loss usually can be helped by treatment of the thyroid disease. Hair loss may occur if male and female hormones, androgens and estrogens, are out of whack.
Many women notice hair loss about three months after childbirth. This loss again is related to hormones. During pregnancy, high levels of certain hormones cause the body to keep hair that would normally fall out. When your hormones return to pre pregnancy levels, that hair falls out and the normal cycle of growth and loss starts again.
Medicines many cause hair loss. This type of hair loss improves when you stop taking the medicine. Medicines that can cause hair loss include blood thinners (also called anticoagulants), medicines used for gout, high blood pressure or heart problems, vitamin A (if too much is taken), birth control pills and antidepressants.
Fungal infections of the scalp can cause hair loss. This infection is treated with antifungal medicine.
Finally, hair loss may occur as part of an underlying disease, such as lupus or diabetes. Since hair loss may be an early sign of a disease, it is important to find the cause so that it can be treated. Information sourced from http://familydoctor.org
