10. Follow a Healthy Diet
The most important beauty habit you can develop to keep your hair, skin, nails, and face looking their best is to follow a healthy diet. Drink 64 ounces of water a day, get plenty of vegetables, fruits, healthy fats, and proteins, and keep the junk out of your diet whenever possible. A healthy diet starts from the inside.
Instead of focusing on your bad habits, develop new, healthy habits. Looking beautiful everyday takes work, but it can be achieved with great results without taking on much more work.
