How to Use

Apply after cleansing & treating hair with Blond Absolu to towel dried hair. Pump 3 to 7 doses of product to towel-dried hair from scalp to ends depending on hair length. Massage gently into the scalp and move through mid-length to ends of hair. Do not rinse.

Pro tip: For ultimate repair and hydration, layer the Huile Cicaextreme over the 2% Pure Hyaluronic Acid Serum.

Stylist Quote

My hair density is thick, so I start with 5 pumps of the 2% HA serum and apply to the pony tail section all the way to my ends. Then apply two more pumps to my face framing and scalp. I then brush my hair for even distribution. After that I apply two pumps of Huile Cicaextreme to my pony tail section, brush my hair again and style my hair.
