A good diet with the adequate amount of vitamins, minerals and amino acids can contribute to the healthier growth of hair. Certain amino acids have been determined to contribute to the thinning and thickening of hair.

In addition to vitamin and mineral supplements, individuals who want to achieve better growth of hair also need to take in the recommended amount of essential amino acids. Some of the amino acids that the body needs to produce healthier hair are methionine, cysteine, cystine, and tyrosine.

• Methionine

Methionine, an essential amino acid, is a powerful anti oxidant. This amino acid is a good source of sulfur which helps in the prevention of hair disorders as well as skin and nail disorders. Methionine is lipotropic, aiding in the breakdown of fats to prevent the buildup of fat in areas such as the arteries and liver.
Methionine prevents the premature loss of hair and also interacts with other substances in the body to detoxify any harmful elements. This amino acid is also a good anti fatigue agent.

• Cysteine

The non essential amino acid cysteine is important for the proper growth of hair. Cysteine has been found to increase the growth of hair by 100%. Cysteine also acts as a powerful antioxidant and protects the body from damage brought about by radiation. Other positive effects brought about by this amino acid are protection of the liver and brain from alcohol, drug, and smoke induced damage. This amino acid also promotes the recovery of the immune system and is helpful in treating rheumatoid arthritis.

• Cystine

Cystine, a non essential amino acid, makes up 10-14% of the skin and hair. This amino acid is plays a vital role in the development of skin and hair. Aside from the effects on skin and hair, cystine may also be used in treating disorders of the respiratory system as well as promote better recovery from burns and surgical procedures. Cystine also stimulates the activity of white blood cells which plays an important role in the body's resistance to diseases.

• Tyrosine

Tyrosine is a non essential amino acid produced naturally by the body. This amino acid produces melanin, the pigment that gives the skin and hair its color. Tyrosine is vital to the body's overall metabolism and to the body's adrenal, pituitary, and thyroid glands. Tyrosine also helps in the production of red and white blood cells, can improve your moods, and is used to treat depression, insomnia, and anxiety.

Amino acid, both essential and non essential, play an important role in hair growth and also in the body's overall health condition. It is best to get these amino acids in the recommended amount your body needs to have more beautiful hair and to live a fuller and healthier life.
