L'Oreal Paris Elvive hair shampoo 400 ml

Contains glycolic acid with a concentration of about 2–3% within what is known as Gloss Complex. This acid gently penetrates the hair shaft and fills the gaps, which improves the softness and shine of the hair. Its formula is sulfate-free, making it gentle on the hair and reducing damage—especially if the hair is colored. It works to close the outer layer of the hair (cuticle) through an acidic pH, which increases light reflection and gives a shine that lasts up to 5–6 washes.
