Diet plays a significant role in the health of your hair. A balanced diet rich in vitamins, minerals, and proteins can promote healthy hair growth and shine. Nutrients like biotin, vitamins A, C, D, E, zinc, and omega-3 fatty acids are particularly beneficial for hair health. Conversely, a poor diet lacking in essential nutrients can lead to hair loss, dullness, and brittleness. It's important to maintain a healthy diet to support strong and lustrous hair.
