hair loss has been one of the main problems that people are facing. Studies show many factors responsible for hair loss. Major trauma (physical or emotional), rapid weight loss, delivering a baby and having an under or overactive thyroid gland are a few of the conditions that speed up hair loss. However hair lost as a consequence of these conditions is regained in time. Women, just as men, have hair follicles, the homes for each hair. These hair follicles are sensitive to male hormones. Male hormones are also produces in women. When a woman's male hormone production increases or when her female hormone production decreases, her hair follicles respond by shedding their hairs and refusing to grow new hairs in their place. This happens to all women, but some are so minimally affected that it's not noticeable. Women's hair loss, unlike the male pattern of hair loss, is a general thinning of hair throughout the scalp, not just at the sides and on the crown. Hair loss can be prevented by not having ones hair colored too often and by avoiding rough combing and brushing and by limiting the number of times you use a blow dryer.
