Product Description
Transform your fine or thin hair into thick, lustrous locks with the L'Oréal Professionnel Serioxyl Thicker Hair Serum. Safe for use on colour-treated hair, this super serum promises and delivers instantly thicker-looking hair. This serum is a game changer for you thicker hair seekers, as it leaves your hair feeling and looking denser and fuller.
The serum works on each individual strand of your hair, thickening each one with Intra-Cylane. The serum creates volume too, so it really is the holy grail for those with finer hair types.
This serum is not just a one-time-only hair thickener. Continuous use will improve the structure of your hair, giving your scalp and follicles the boost they need to stimulate strong, healthy hair growth. You can use a little of this serum on non-hair-washing days too to add some extra oomph.
First use the L'Oréal Professionnel Serioxyl Clarifying & Densifying Shampoo For Natural Thinning Hair. Complete the set with L'Oréal Professionnel Serioxyl Thickening & Detangling Conditioner.
