One of the main reasons for ridges is the lack of natural oils in the skin. Moisturize your nails with any nail oil or olive oil daily to restore the oil balance. The better moisturized your nails are, the more resistant they will be against ridges. Keep your hands and feet moisturized with a lotion or cream. In addition, make sure that you drink at least 8 glasses of water every day, so that you are hydrated internally.
Malnutrition can also lead to ridged nails. Nails need vitamins and proteins for healthy, ridge-free growth. A diet that is rich in vitamins and proteins can lead to overall improvement in your health and physique, which will also reflect in your nails. Nails themselves are made up of hard protein. Inculcate a greater amount of fruits and vegetables in your diet as they are the source of valuable vitamins, without a lot of fat count. Vitamin supplements can also aid in covering up nutritional deficiencies. However, it is always best to cover up the natural way.
The hygiene and cleanliness of your nails also has a great effect on their health. Avoid using your nails for scraping any surface or using your nails as screws. Make sure you avoid direct contact with any chemicals that can weaken your nails; this includes some hard cleaning products around the house. Nails are very sensitive to chemical exposure. Clean them well regularly and moisturize after every wash. When you file your nails, make sure that you do it smoothly. Buy a buffer kit for your nails and buff the surface. The buffing will cover the ridges to a great extent. Polish your nails after buffing to conceal any remaining ridges, and get a neat look. A professional manicurist can also help you in this regard.
