Product Description
Update your hair care routine with the innovative L'Oréal Professionnel Serioxyl Thickening & Detangling Conditioner. As part of the Serioxyl range, this conditioner is perfect for thinning hair types that need a little boost in the volume department.
Specially designed for thin, fine and lifeless hair, this nourishing formulation helps add body and volume to your tresses. To do so, it lifts from the root to ensure a fuller, thicker look. Better yet, it helps detangle any tricky knots and adds a much-needed burst of hydration without weighing down your strands.
Enriched with polysorbate 21 and magnesium sulphate, this formula reinvigorates your limp locks for fresh-feeling, healthy-looking results. Plus, it's hypoallergic which makes it suitable for sensitive scalps.
Start your routine with the L'Oréal Professionnel Serioxyl Clarifying & Densifying Shampoo For Natural Thinning Hair. Works well with L'Oréal Professionnel Serioxyl Denser Hair Treatment. You might also like L'Oréal Professionnel Serioxyl Thicker Hair Treatment.
