If you're someone who loves to play around with hair colour, whether permanent or the balayage type, you may have experienced the harmful effects of metal deposits on your hair. Metals like copper and iron in the water can create oxidative stress on your hair, leading to a dull and damaged look. This is where L'Oreal Professionnel Metal Detox Serum In Oil comes in. This excellent hair oil contains a unique blend of nourishing oils that helps remove harmful metal deposits from your hair. The serum-in-oil formula penetrates deep into the hair fibres to protect them from harmful metal deposits, leaving your hair looking healthy and shiny. And because we all know how damaging heat styling can be for our hair, this serum in oil provides an added layer of heat protection up to 230° C, so you can enjoy fabulous hair sans the damage.
