Causes of Hair Loss

Article by jethrowe

Most people normally shed 50 to 100 hairs a day. But with about 100,000 hairs in the scalp, this amount of hair loss shouldn’t cause noticeable thinning of the scalp hair. Gradual thinning is a normal part of aging. However, hair loss may lead to baldness when the rate of shedding exceeds the rate of regrowth, when new hair is thinner than the hair shed or when hair comes out in patches. Genetic hair loss isn’t due to excessive amounts of hair falling out, as many believe, but to an insufficient amount of hairs growing back to replace the hairs that have been shed.

Hormonal problems may cause hair loss. If your thyroid gland is overactive or under active, your hair may fall out. This hair loss usually can be helped by treatment thyroid disease. Hair loss may occur if male or female hormones, known as androgens and estrogens, are out of balance. Correcting the hormone imbalance may stop your hair loss.

During pregnancy, high levels of certain hormones cause the body to keep hair that would normally fall out. When the hormones return to pre-pregnancy levels, that hair falls out and the normal cycle of growth and loss starts again.

Hair loss may also occur if you are taking medication. Only certain medications may cause hair loss. However when the medication is stopped your hair will begin to grow back. Medicines that can cause hair loss include blood thinners, birth control pills and antidepressants, medicines used for gout, medicines used in chemotherapy to treat cancer.

Male-pattern baldness is the most common cause of hair loss in men. Men who have this type of hair loss usually have inherited the trait. Men who start losing their hair at an early age tend to develop more extensive baldness. In male-pattern baldness, hair loss typically results in a receding hair line and baldness on the top of the head.

Infections, such as ringworm, can invade the hair and skin of your scalp, leading to hair loss. Once infections are treated, hair generally grows back. Ringworm, a fungal infection, can usually be treated with a topical or oral antifungal medication.

Having inadequate protein or iron in your diet or poor nourishment in other ways can cause you to experience hair loss. Fad diets, crash diets and certain illnesses, such as eating disorders, can cause poor nutrition.

One of the most common forms of hair loss is caused by an auto-Immune disorder called Alopecia Areata. This is a disease that causes the white blood cells to attack the hair follicles. The result is a temporary loss of hair.

Head trauma like chemical, severe damage from a blunt object, and over-exposure to extreme low temperatures run the risk of total and permanent hair loss. Wearing a tight helmet over a long period of time is technically not a head injury, but the continuous pressure it causes, can lead to permanent hair loss as well.
