Ladine has a professional-only relaxer process that begins with Prefix – a “polyfilla” for hair that ensures an even penetration of chemicals. The relaxer is followed by a Bio-complex treatment that penetrates the hair while the cuticles are still open, and lowers the pH of the hair that returns it close to its original pH. After this treatment the hair appears jet-black, with cuticles closed and aligned. The neutralising shampoo then returns the hair to its original pH, leaving it perfectly balanced, moist and shiny.
