TECNI.ART Siren Waves Defining Cream from L'Oréal Professionnel. Suitable for all hair types, its unique elasto-cream texture creates ultra-defined curls and enhances the hair's natural shine for salon-style results. Can be applied to dry hair to revive curls throughout the day. DIRECTIONS Apply 1 to 2 hazelnut-size drops onto shampooed and towel dried hair. Spread evenly with a comb on to lengths and ends. For smooth results, blow-dry hair. To control curls’ definition, allow to dry naturally.
