My nails are dry and brittle with ridges, and the skin around my nails is dry and hard.
Some women have harder, more brittle nails simply due to genetics.
EFA's are essential in controlling body oils that keep skin soft, smooth, and youthful. Lecithin, found in egg yolks and some other vegetables, enables the body to absorb essential fatty acids and is itself a rich source of EFA's. Stress and environmental pollutants can contribute to dryness also. Your body requires B vitamins to function properly and will take these from nutrient stores in the hair, skin, and nails if it does not receive its daily requirements through food or supplement sources. The result is dry and brittle hair that breaks easily, as well as severely dry skin around your nails.
