OI Shampoo: Gently massage into scalp and rinse thoroughly. Follow with OI Conditioner.
OI Conditioner: Following OI Shampoo, apply evenly to damp hair from lengths to tips, let rest 2-3 minutes, then rinse thoroughly. Follow with OI Milk or OI Oil.
OI All in One Milk: Apply 10-15 sprays to washed, towel-dried hair. Do not rinse, and proceed with styling. It is possible to apply the product as a moisturizing finish, vaporizing it directly on the hands and then distributing it evenly on the hair, if they are particularly dehydrated.
OI Oil: Before styling - apply 2-3 pumps of oil to towel-dried hair, and proceed with drying. As a finishing touch - apply 2-3 pumps of oil to the lengths and ends of dried hair (for fine hair, start with 1 pump).
