Overview of Hair Fall

Hair loss is a very common condition and affects most people at some time in their lives. Androgenetic hair loss is seen in both men and women but is worse in men.
Thyroid disease, anemia, protein deficiency and low vitamin levels may cause hair loss. Alopecia areata is a relatively common cause of hair loss that usually resolves on its own. Medications indicated for hair regrowth include minoxidil and finasteride, But it has major side effects in long term use.

Prevention of hair loss include

Good hair hygiene, regular shampooing and good nutrition.
Medical health screening for hair loss may include blood tests such as complete blood count (CBC), iron level, vitamin B and thyroid function tests (TFT).

Causes of Hair loss

Hormonal Changes - Hormonal changes and imbalances can cause temporary hair loss. This could be due to pregnancy, childbirth or the onset of menopause.
a) Androgenetic hair loss is seen in both men and women but is more dramatic in men.
b) Thyroid disease, anemia, protein deficiency, chemotherapy and low vitamin levels may cause hair loss.
c) Alopecia areata is a form of hair loss produced by the autoimmune destruction of hair follicles in localized areas of skin.
Stress - Both emotional and physical stress (such as a serious illness or recovery from surgery) have been associated with hair loss. It is possible that stress induces hormonal changes that are responsible for hair loss since hair loss is a known consequence of other hormonal changes due to pregnancy, thyroid disturbances, or even from taking oral contraceptives.
