PRODEW 500

PRODEW 500 is an aqueous solution of amino acids, Sodium PCA and Sodium Lactate , developed by the manufacturer for hair cosmetics. According to their data, it helps hydrate hair, improve its strength and shine, and support colour retention after dyeing. In a formulation it functions as a humectant and conditioning ingredient without silicones, making it suitable for shampoos, conditioners and masks. Besides Sodium PCA and lactate, it contains arginine, aspartic acid and a blend of further amino acids that the manufacturer formulated to mirror the proteins of the hair cell membrane complex (CMC) . The manufacturer tested the effect of individual amino acids on multiply bleached hair and reports the results in their technical documentation.

In a hair product they reduce the feeling of dryness; in facial cosmetics they work as a humectant. Conditioning – the manufacturer categorises the effect by amino acid type. According to their data, basic amino acids (arginine, histidine) improve strength and shine; neutral ones (glycine, alanine, serine, valine) improve combability and smoothness of dry hair; the acidic aspartic acid improves combability of wet hair. Colour retention – in the manufacturer's study, a conditioner with Sodium PCA applied after dyeing improved the development of the red shade of semi-permanent colour.
