L'Oréal Professionnel Serioxyl Thicker Hair Serum gets to work bulking up your clients' hair.

This Thicker Hair Serum produces an instant thickening effect for thin or fine hair.

It has been enriched with Intra-Cylane, a thickening molecule born of ten years research to reveal hair that looks thicker and appears fuller to the touch.

Apply a few pumps to wet hair, evenly along the lengths and ends. Leave to dry naturally or blow dry using a hairdryer.

Available in 90-ml bottle.
