While hair grows at a steady rate of roughly 1/2 inch every month, people can gain more length by keeping their hair healthy. A balanced diet, proper hair care products and regular trims are keys to maintaining hair health.
Protein and omega-3 fatty acids promote hair health and growth. Eggs and fish are both rich in protein and omega-3s. Likewise, hair needs B vitamins, cysteine, vitamin C and biotin to grow. These vitamins can be found in foods or in multivitamins, especially ones targeted for hair, skin and nails.
People also need to prevent hair from breaking as this doesn't allow it to show new growth. Heat styling with blow dryers, curling irons and flat irons damages the hair. This can cause breakage. Before using such tools, apply a heat protectant product. Likewise, using shampoo and conditioner to moisturize and strengthen hair promotes its health.
A healthy scalp also promotes healthy hair, so massaging and conditioning the scalp is another recommendation. In fact, massage promotes circulation, which stimulates hair follicles. Apply a warmed hair oil or conditioner to the hair. Using a circular motion, massage the scalp for up to 5 minutes before rinsing with cool water. This massage is repeated weekly for the best results.
Regular trims also keep hair from breaking due to split ends. Trim a 1/4 inch every six to eight weeks.
