L'Oreal Paris Serioxyl Denser Hair Serum 90ml

L’Oréal Professionnel Serioxyl Denser Hair Serum is a scalp-targeted density activator designed to help hair look denser when you’re dealing with thinning and loss of density. The treatment is applied directly to the scalp and used as part of a daily routine, with results focused on improving the look of density over time.

Formulated with 5% Stemoxydine, it works alongside Neohesperidin to support a denser-looking appearance. L’Oréal Professionnel positions this as a three-month regimen, with claims of more hair per cm² when used as directed. Boots also notes that the formula is concentrated with 5% Stemoxydine and enriched with Resveratrol, supporting improved follicle renewal as part of the hair cycle.

For application, retailers describe quick, targeted use on the scalp roots, with no need to rinse after it has absorbed (leave it to dry). For the most accurate ingredients, always refer to the product packaging; for example, Boots lists alcohol denat and resveratrol among the ingredients.
