Keratin makes up around 80% of the hair structure which is composed of two parts, the external cuticle and the internal cortex. Keratin, the name given to the cystine containing proteins found in hair fibres, is the main component of both of these regions of the hair.
Keratin Strengthening Conditioner intensely hydrating conditioner repairs the cuticle and smoothes it for ultra glossy and shiny hair.
