Healthy, full hair is a result of hair follicles absorbing vitamins and other nutrients. Many vitamins essential to healthy hair are found in the foods we eat. Sometimes we do not get all of the nutrients needed in our diets, so taking additional vitamin supplements can help us grow thicker and fuller hair.
Incorporate protein-rich foods into your diet. Foods such as lean meats, beans and peanut butter are very high in protein, which helps hair grow in fuller and stronger. Eating foods rich in protein can also speed up hair growth.
Add foods like salmon and dark green vegetables into your diet. According to Andrea Giancoli, MPH, RD, a dietitian for the American Dietetic Association, having a healthy scalp is important for hair to look full and shiny. Salmon is filled with omega-3 fatty acids and protein, two important elements for healthy scalps. It is also high in iron and vitamin B-12. Dark green vegetables are high in vitamins A and C, which are needed for your body to produce sebum, an oil that is considered the body's natural conditioner. Sebum is beneficial not only to the scalp but to the hair follicle as well.
Incorporate vitamin supplements in your diet. Vitamin B-12 can be taken to help hair grow thicker. It is known to prevent hair thinning and loss, which helps make hair look thicker. In addition, vitamins A, C, E and B3 (Niacin) can be taken as supplements to help hair grow thicker. They improve circulation in the scalp, which stimulates hair growth.
Switch to vitamin-fortified shampoos and conditioners. Many shampoos and conditioners are fortified with vitamins A, C and E. Massage them into your scalp when you wash your hair.
