Healthy hair depends not only on external care but also on an adequate supply of nutrients. Biotin, zinc and selenium contribute to the maintenance of normal hair, while copper supports normal hair pigmentation. Vitamin B6 contributes to normal cysteine synthesis, and vitamin C improves iron absorption.
Key Nutrients for Hair Strength
Biotin and zinc support the maintenance of normal hair.
Cystine and methionine are sulphur-containing amino acids used by the body in the formation of structural proteins such as keratin.
Vitamin B6 supports normal cysteine synthesis, while vitamins C and E help protect cells from oxidative stress.
A supplement is most useful as part of a balanced diet or when a specific nutritional need has been identified. Taking excessive amounts of individual vitamins or minerals does not necessarily improve results and may be counterproductive.
