Acidic Color Gloss Activated Glass Gloss Treatment is a rinse-out gloss treatment for color-treated hair, and what sets it apart from a typical deep conditioner is that it's actually activated with a small amount of hydrogen peroxide, paired with an acidic pH complex, so it works more like an in-salon glossing service than a leave-behind coating. The acidic formula is designed to sit at a pH that's compatible with color-treated hair while temporarily smoothing the cuticle, and the treatment also carries apricot kernel oil, soybean oil, and conditioning amino acids to soften hair as it rinses clean.
Redken's own product information reports a meaningful jump in shine after a single use, with the glossy finish holding up for a few days before it starts to fade — which is why it's positioned as a weekly maintenance step rather than a daily or leave-in product. It's meant to slot in after a normal shampoo, on towel-dried hair, as a periodic top-up for people who color their hair and want to keep tone and shine looking fresh between salon visits.
Because of the peroxide content, it's handled a bit differently than an ordinary mask or conditioner:
- Apply to towel-dried hair after shampooing, with gloves on
- Leave on for the directed time, then rinse thoroughly — it is not left in
- Avoid eye contact and rinse immediately if the product gets in eyes
- Intended for roughly weekly use as a maintenance step, not a daily product
