What causes hair loss; Whenever hair breaks or starts falling out, people often think of spending money on expensive hair treatments at the parlour. However, experts suggest that it is very important to understand the root cause of hair loss.

Today, we will explain which essential vitamin deficiency can cause hair loss. Vitamin D deficiency can affect not only your physical health but also the health of your hair.

If hair loss is caused by vitamin D deficiency, no matter how many expensive oils, shampoos or hair treatments you use, it will not be resolved until your vitamin D deficiency is corrected.

For those recovering from vitamin D deficiency, simply basking in the sun is not enough. Along with spending 15 to 20 minutes in the sun every day, it’s also important to include some vitamin D-rich foods in your diet.

Yogurt, oatmeal and oats can be consumed to overcome vitamin D deficiency. Mushrooms and eggs are also rich in vitamin D. If you want, you can also take vitamin D supplements after consulting a doctor.
