A balanced diet is a crucial step in the prevention of hair loss and the protection of the healthy hair structure. Hair follicles receive blood flow and get nutrients from the blood, and therefore our hair needs all types of nutrients to receive the vitamins and minerals it requires. Hair has a protein structure, and it gets nutrients from protein rich food. Consuming enough red meat is very important for healthy hair. If you are a vegetarian and take supplements, it is better to also take protein supplements to meet the needs of your body and hair.
