6. Lack of Sufficient Protein
Our nails and hair are formed with protein, and if your daily diet lacks sufficient amount of protein, you are highly likely to experience hair loss, hair damage and brittle nails.
Usually, this tends to occur amongst individuals who suffer from eating disorders or have severe dietary limitations.
If you’re a vegetarian, you don’t have to deprive yourself of protein entirely, for it doesn’t always have to come from meats. You can also obtain protein from tofu, lentils, beans and spinach amongst many other sources.
You can also add foods, like wheat germ, red peppers, pork, and broccoli that contain cystine to your daily diet, which is basically the amino acid that generates keratin.
