In addition to the common male and female patterns, the following are other types of hair loss some of which are temporary:
Alopecia areata - bald patches develop on the scalp, beard, and possibly eyebrows. eyelashes may fall out as well. This is thought to be an autoimmune disease, where the immune system attacks the hair follicles and leads to hair loss on the scalp and other parts of the body. However, the hair follicles are alive so there is potential for hair to regrow when the underlying problem has resolved. Growth may occur even without treatment and even after many years.
Tinea capitis - is hair loss due to fungal infection of the scalp. This is easily treated with antifungal medicines.
Hormonal changes - an over-active or under-active thyroid gland may cause hair loss. This hair loss stops once the thyroid disease is treated.
Female or male hormone (estrogen and androgen) imbalance can be the cause of hair loss. Once this imbalance is corrected hair loss may stop. Some women may experience hair loss a few months after they've had a baby. This loss is also due to hormonal changes.
Telogen effluvium - is temporary hair loss, which can occur after a serious illness, major surgery or emotional or physical stress.
Anagen effluvium - is hair loss due to treatment with chemotherapy medicines. These medicines target rapidly dividing cells, so affects the actively growing hair cells. Hair grows back after the treatment is finished. This type of hair loss also occurs with radiation therapy but it is localized to the area of treatment. so if treatment is in the hip area you will lose hair in that area but not the hair on your head.
Traction alopecia - certain hairstyles such as when you pull on your hair tightly can cause scarring of the hair follicles. If pulling is stopped before scarring to the scalp then your hair will grow back normally. Nervous habits such as continual hair pulling or scalp rubbing can also cause scarring and ultimately permanent hair loss. Excessive shampooing and blow-drying can also cause hair loss.
