SERIOXYL is the ultimate range for thinning hair from L'Oreal Professional Hair thinning often goes hand in hand with scalp sensitivity, and the two new Serioxyl shampoo and conditioner formulas (for coloured & non-coloured hair) are all hypoallergenic to cater for sensitivity. These products are perfect to use in conjunction with our Serioxyl Serums.

1. DENSER HAIR SERUM - a daily treatment for those wanting denser, more luscious hair. It's powered by Stemoxydine 5% + Resveratrol.

2. THICKER HAIR SERUM - an everyday fibre thickening serum that leaves hair looking thicker*. *Instrumental test Thicker Hair versus classic shampoo. For instant coverage, try our NEW Serioxyl Volumising & Bodifying Coloured Sprays.
