L'oreal Serie Expert Renew C is a alpha hydroxy acid-based pre-shampoo repairing treatment for very damaged hair. This pre-treatment targets the cortex and cuticle to strengthen keratin links and reduce porosity to deeply renew chemically-damaged hair. Renew C is a pre-shampoo concentrated repairing treatment for fragile, brittle and devitalised, lifeless hair. This in-salon treatment is for deep down care, which penetrates to the very heart of the hair fibre and provides a firming and strengthening action.
L'oreal Serie Experts In-Salon Pre-Treatments target the cortex (Zone C) to neutralize weak, negatively-charged keratin bonds that have been broken down by a chemical process. Hair's internal structure is reinforced with reduced porosity, optimizing a color or smoothing process for radiant shine and long-lasting protection of color.
