This conditioning treatment uses hydrolyzed keratin to make hair stronger and healthier, while olive oil and amino acids tame multicultural and naturally textured hair and add slip for blow drying and other heat styling. Our unique leave-in formula contains Panthenol that nourishes hair for long-term conditioning and a smooth shine that lasts all day. Use as an entire system in conjunction with Culture shampoo and conditioner (Step 1and 2) to seal in their added nutrients and maintain your style for the long haul.
