Reaction Treatment is a multi-step, deep-conditioning, frizz-taming, professional hair treatment aimed at repairing and restoring the oils and proteins that the hair has lost from perms, bleaches, highlights, colors, heat damage, environmental / UV damage and even over-processing. By replenishing the 3 key components of the hair: Moisture, Oil, and Proteins, the Reaction Treatment is perfect for frizz-prone hair types whether the hair is straight, natural, or curly. (Reaction Treatment is completely formaldehyde-free and will not alter curls.) It’s a simple system that any professional can complete in just 45 minutes. Reaction Treatment can be used as a stand-alone treatment or can be added on to any salon service (haircuts, colors, perms, iStraight System etc.) to complement and enhance the results with healthier-looking, beautiful texture.
