The right vitamins and minerals play a major role in keeping your hair healthy. Any nutritional deficiencies can lead to thinning hair or even total baldness. It is a well known fact that an under active thyroid can result in frizzy or brittle hair while an overactive thyroid turn hair greasy and limp.
Hair loss usually develops gradually and may be patchy or diffuse (all over). Roughly 100 hairs are lost from your head every day. The average scalp contains about 100,000 hairs.
Some women also develop a particular pattern of hair loss due to genetics, age, and male hormones that tend to increase in women after menopause. The pattern is different from that of men. Female pattern baldness involves a thinning throughout the scalp while the frontal hairline generally remains intact.

Your hair ultimately reflects the overall condition of your body. If your body is healthy and well nourished, your hair will be your shining glory.
If you are having any health problems or suffering from any nutritional deficiencies, your hair may stop growing or show damage.
Unfortunately many people are not aware of the fact that while hair can be extraordinarily resilient, once it has emerged from your scalp is has no facility for renewing itself. It is considered to be dead protein.
Hair loss from menopause or childbirth often returns to normal 6 months to 2 years later
