L'Oréal Paris Elvive Glycolic Gloss Leave-In Serum 150ml is specifically formulated to restore the luminous shine of the hair. It particularly targets porous, dull hair that lacks shine, targeting the hair cuticle with an innovative 14% Gloss Complex. This complex features glycolic acid and, together with a unique pH, the formula works by sealing the hair cuticle and improving the quality of the hair fiber from the inside for long-lasting gloss. When the cuticle is closed, light reflects off the hair in an ideal manner, which is precisely what this product aims to achieve. This process transforms damaged cuticles with low light reflection into laminated cuticles that reflect light for intense shine. The result? Hair that is not just twice as shiny but also 88% silkier, and with a 75% reduction in frizz. With its ability to repair and seal the hair fiber, this serum offers incredible benefits. It ensures that your hair not only regains its shine but also its smoothness and overall health. Whether you're dealing with porous, dull hair or simply looking to enhance your hair's natural gloss, this product offers a great solution. It stands out as an essential gloss treatment for anyone looking to revitalize their hair and enjoy its natural beauty.
