Sebastion's Cellophanes Hair Gloss in Espresso Brown imparts pure shine by increasing the reflectivity of each strand of hair for an overall brilliant effect. This demi-permanent hair gloss is available in multiple translucent shades plus a clear gloss coating, allowing for custom, high-gloss color treatments that last up to four weeks.These Cellophanes nourish and strengthen the hair while coloring and adding glossy shine. They also protect locks from UV rays and use new hair technology that deposits color on the outside of each strand rather than penetrating the fiber, making them ideal for color-treated and virgin hair.
