Evening Primrose Oil for weak or brittle nails

Weak or brittle nails usually don't signal any serious medical problem. They are typically caused by excessive exposure to detergents and water. Over-filing and over-buffing nails can also weaken them. Many people report that taking supplemental gamma-linolenic acid (GLA) helps to strengthen nails, as well as improve skin conditions and promote the growth of healthy hair. This essential fatty acid is hard to come by in the diet, and the best natural sources are found in evening primrose oil and Black Currant Oil. It is recommended to use Evening Primrose Oil in doses of 500 mg twice a day (or follow the directions on the package) for six to eight weeks.
