A number of factors could be accelerating hair loss.
1.Poor nutritional status due to consumption of unbalanced meals(deficient in nutrients like protein, iron, zinc, B-complex vitamins,vitamin E, and vitamin A) for prolonged periods of time may affect overall health of the hair. In addition to this, fad diets, crash dieting and eating disorders may also contribute to hair loss. This type of hair loss can be reversed by adequate nutrition.
2.Stress related to an illness or surgery can also cause hair loss but it is usually temporary. Stress-related hair loss is temporary; it reverses once the stress goes away.
3.Certain medications like anticoagulants, anti depressants, medications used in the treatment of high blood pressure, gout and Cardiovascular problems also may be responsible for triggering hair fall. When the medications are discontinued, hair loss can be restored.
4.Hormonal problems, Thyroid disorders, underlying disease (diabetes, lupus); infections of the scalp (fungal, ringworm) may also result in excess hair fall. This type of hair fall can be reversed by treating the underlying cause.
5.Trichotillomania,a mental illness where in a person is habituated to pulling or twisting hair from the scalp, eyebrows, eyelashes or other areas of the body could also contribute to the problem of hair loss.
