Cystine is essential in hair
Cystine is a sulphur-containing amino acid, which is an essential component of keratin.
It is an essential nutrient found in the material that makes up hair and nails.
Scientific studies have demonstrated that high doses of cystine significantly increase the speed of growth of follicles and the diameter of the hair strand1.
CYSTIPHANE nutritional supplements are very rich in cystine.
