REVOX B77 PLEX HAIR PERFECTING TREATMENT is the 3rd step of the advanced REVOX B77 PLEX Hair Rebuilding System. This concentrated professional product is developed to replenish damaged and color-treated hair from the inside out. Unlike conditioning products, it works by restoring the bonds in the hair fibre, improving texture, and protecting hair structure from breakage. The hair is stronger, shinier, and smoother from the first use. Color-safe & beneficial for all hair types. Use before shampoo, 1-3 times a week on damp, towel-dried hair. Apply a generous amount from roots to ends of the hair, spreading it with a comb or fingers until sufficiently and evenly saturating the hair. After 15-20 minutes, rinse thoroughly with water (don’t leave in overnight) Shampoo and condition your hair as usual. For best results, use REVOX B77 PLEX BOND CARE SHAMPOO - Step 4 and REVOX B77 PLEX BOND CARE CONDITIONER Step 5
