L-cysteine (sulfur-containing amino acid) is one of the main components of hair (18%), nails (14%), and, to a lesser extent, skin (2% to 4%). L-cysteine is found in the keratin of hair and nails. It accelerates the proliferation of cells rich in keratin, which has a positive effect on the growth of hair and nails. High levels of cystine appear, mainly in the hair, 4 to 6 weeks after taking the tablets.

Vitamin B6 is a vital factor for the utilization of L-cysteine. It allows the incorporation of L-cysteine into the areas where keratin is formed. The nutritional balance between L-cystine and vitamin B6 is essential because a B6 deficiency leads to a reduction in the incorporation of L-cysteine into hair and nails.

Arginine is an amino acid found in high concentrations in active hair follicles. It acts synergistically with L-cysteine, complementing its effects.

Zinc is also essential for the formation of keratin. Additionally, it inhibits an enzyme responsible for hair loss. Its action is proven and with much greater potential than the presence of vitamin B6.

4 tablets per day should be taken with meals for a period of 2 to 3 months.
