“ This leaves hair feeling smooth & weightless, ” says Adam Reed, who uses it on Ellie Goulding. “ Apply it while hair is damp – a little less for damp hair & a little more for thick.” Think of it as the hair equivalent of a makeup primer. L' Oréal Professionnel Tecni Art Liss Control + gives up to 24-hour anti-frizz protection, softness & natural-looking shine to any style. Best for thick, frizzy, wavy or difficult to manage hair. Style Tip: Always apply L' Oréal Professionnel Tecni Art Liss Control + with hands to mid-lengths & ends of hair; serum applied too close to roots can create an oily look. Directions for use: Rub a few pumps of L' Oréal Professionnel Tecni Art Liss Control + between hands & work through the lengths of towel-dried hair. Blow-dry smooth or leave to dry naturally.
