L-cysteine is an amino acid that can help maintain healthy hair growth. Amino acids are the building blocks of protein in the body. L-cysteine bonds with other proteins to form hair shafts. These bonds are what make L-cysteine an important part of hair growth.

L-Cysteine

L-cysteine is a sulfur-containing amino acid. In addition to maintaining healthy hair, L-cysteine aids in the detoxification of the body by binding to substances left behind by drugs, nicotine or alcohol and allowing them to be removed in the body's normal cleansing processes.

Effects

L-cysteine promotes hair growth by increasing the diameter of the hair shaft. The percent of increase will differ for each person.

Food

L-cysteine can be found in protein-rich foods. Chicken, turkey, broccoli, milk and eggs are all good sources of L-cysteine.

Supplements

L-cysteine can also be found in synthetic form. It is most commonly taken in pill form but it can be used in liquid form. Once digested L-cysteine is released into the bloodstream. Once in the bloodstream L-cysetine is absorbed by the scalp and passed through the hair shaft.

Side Effects

Side effects from L-cysteine are rare, however it can interfere with insulin. If you are taking insulin consult with your doctor before incorporating L-cysteine into your diet.
