Correcting a hormone imbalance may prevent further hair loss. Hypothyroidism can cause it, especially thinning of the outer third of the eyebrows. Tumors and skin growths can also induce localized baldness.
Go a more natural way with treatment if possible; taking hair loss drugs require many months of exposure to chemicals. Propecia is available with a prescription; comes in pill form, is only for men and may take up to six months before you can tell if it is working. Minoxidil is a very expensive drug, costing about one hundred dollars per month for daily treatment.
Hair loss treatments and remedies range in price from free to expensive. Stress reduction can be helpful in slowing loss. Please be aware there are side effects and serious side effects sometimes with the drugs that are commonly used for hair loss.
