1) Hair grows about half an inch per month normally, but an unhealthy scalp can slow growth. Maintaining scalp health and a nutritious diet are essential for good hair growth. 2) Getting vitamins, proteins, sulfur and nutrients from food, along with 8-10 glasses of water daily, helps nourish hair. Massaging the scalp weekly with oil mixtures also stimulates blood circulation for growth. 3) Regular brushing, protecting from sun, taking vitamin supplements, getting enough sleep, and using hair masks weekly can further support healthy hair and optimal growth.
