3. Vitamin Deficiencies
The body relies on vitamins and minerals for a variety of functions that help the body maintain homeostasis. Vitamin K, vitamin A, and vitamin D are essential for the health of your hair and fingernails. However, many people do not get enough of these specific three types of vitamins, resulting in a thinning of the hair, and possible hair loss.
If you start to notice ridging on your fingernails combined with hair loss or any other adverse skin symptoms such as it your dry skin visit your doctor for a blood test. Your doctor will draw a blood sample and send it to a lab for analysis. A few days later, the doctor will receive the results of your test, and they will be able to tell if you have any vitamin deficiencies that are leading to ridging in your nails.
If you do discover nutrient deficiencies, then you can bring these levels back up to par using a multivitamin supplement designed to increase levels of these micronutrients in your bloodstream.
