This double pack treatment restores hair pH, seals cuticles, and delivers up to 72 hours of sleek, frizz-controlled shine with amino acids and conditioning agents. Use weekly on damp hair.

Citric Acid works by restoring the hair back to its healthiest pH [pH 4.5-5.5], sealing in the cuticle, so your shine is locked-in and your hair left incredibly glossy and smooth. The Exclusive Acidic Shine Complex is formulated with a blend of amino acids and conditioning agents that deposit glossing molecules, further supporting the look of healthy, glass-like shine with a single application.

Using weekly after shampooing, apply the treatment from mid-lengths to ends of damp, towel-dried hair and leave on for 5 minutes. Then rinse. Apply the Acidic Color Gloss Conditioner to lock in moisture, rinse. For added protection and extended colour-vibrancy and shine, seal your routine with the Acidic Color Gloss Heat Protectant Spray. Use this treatment 1 week after glosses, toners and permanent colour services. Not recommended for use after vivid semi-permanent, or temporary colour.
