4. Hair and Nail Health
Adding walnuts to your regular diet can also help improve your hair and nail health. These tasty nuts can help to strengthen the hair follicles and also can help to prevent dandruff from forming. When the hair follicles are strengthened, it can lead to hair that is stronger, longer, and thicker than ever before. The reason that walnuts are so great for your hair and for your nails is because they contain a high amount of biotin, which is also known as vitamin B7.
Biotin is thought to be very important when it comes to the growth of hair and nails. In addition, walnuts contain a good amount of vitamin E. Vitamin E is also important when it comes to giving your hair a healthy shine and making your nails much stronger. One more great thing about walnuts is that if you want to give your hair some natural highlights, the husk is perfect.
