This conditioning treatment uses hydrolyzed keratin to make hair stronger and healthier, while olive oil and amino acids tame unmanageable 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 1 and 2) to seal in their added nutrients and maintain your style for the long haul. DIRECTIONS: Rub against both palms and massage into wet hair and scalp evenly from root to tip. Blow-dry or pat dry with a clean towel and style as normal.
