Pregnancy can have a wonderful effect on a women's hair. From the fourth month of pregnancy the hair is usually at its best. It is shinier, more abundant, more manageable, less greasy, less dandruff and scalp problems. This improvement in the hair is because of the increase on female sex hormones (mainly estrogen).

But after the baby is born, there is often a great loss of hair due to these hormones falling back to the normal level. The hair, which is lost after childbirth, is the hair that would normally have fallen out during nine months of pregnancy but didn't and will now fall out from the second to the sixth month after the baby's birth.

Post-natal hair loss affects approximately 40% of all women with children and can be very frightening and upsetting experience. Although new hair is not produced, follicles remain alive, suggesting there are possibility of new hair growth. If left untreated, it will become permanent hair loss. Hair loss is also evident in breast feeding women.
