3.Cause: Low Thyroid Levels
Sweat is your body’s natural moisturizer. Low levels of the thyroid hormone, called “hypothyroidism,” lessens how much sweat your body makes. The result is drier hair, skin, and nails. Along with brittle nails, you might have other symptoms like aches and pains, fatigue, weight gain, and memory problems.
4.Cause: Anemia
The most common cause for anemia, or a low red blood cell count, is not enough iron in the blood. It can happen when you lose too much blood. You can also get it if you don’t get enough iron in your diet or have a condition that keeps you from absorbing it. Anemia can make your nails brittle or cave inward in the shape of a spoon.
