Among the culprits are permanents, emotional stress, thyroid disease, skin disease, and drugs. Hair loss or thinning sometimes occurs at menopause, while thinning hair can be a problem for some women up to two years after pregnancy. If your hair loss is due to a condition such as thyroid disease, diagnosis and treatment will probably reverse the loss. Treatments for hair loss in patches aren't as effective. Even though steroid therapy sometimes helps, hair loss usually resurfaces when treatment stops.
Good nutrition is always a plus.
But there's no evidence that vitamins, food supplements or other products will prevent baldness or grow hair. The Food and Drug Administration has banned the sale of prescription creams and lotions promoted as hair-growing preparations. You'll need to massage it into your scalp twice a day for four months to get any results and probably use it indefinitely to keep new hairs intact. Also remember that the treatment doesn't work for everyone. Avoid pulling your hair or massaging your scalp vigorously while you're shampooing.
