It helps improve the look of the hair fibre density and is ideal for use on fine, noticeably thinning hair. As part of the L'Oreal Professionnel Serioxyl programme, this bodifying conditioner for natural hair helps towards creating visibly thicker and fuller looking hair in an instant without weighing it down.
