Amino acids, fatty acids, and vitamins all contribute to healthy hair.
Amino acids make up proteins. The most important amino acids for hair growth are cysteine and methionine. You will find methionine in sesame seeds, fish, and meats; cysteine is in eggs, milk, cheese, chicken, turkey, duck, whey protein, red peppers, garlic, brussel sprouts, oats, and wheat.
Fatty acids are in natural fats and oils. Effects of a fatty acid deficiency include dry hair, change in hair colour, and a red and flaky scalp.
