Redken Acidic Color Gloss Rinse-Out Glass Gloss Treatment for Color-Treated Hair — Intense Shine & Conditioning

Redken Acidic Color Gloss Glass Gloss Treatment is a professional-strength, at-home rinse-out gloss that seals the cuticle and delivers intense, salon-caliber shine to color-treated hair.

This pre-activated, ultra-acidic formula was developed to restore reflective, glass-like shine and boost conditioning for hair that’s been colored or glossed. The blend of citric acid, hydrogen peroxide and apricot oil works at the cuticle level to smooth the hair surface and lock in a hydrated, glossy finish that lasts when used as part of the Acidic Color Gloss routine.

How does this treatment improve shine without coating hair?

The formula works by temporarily adjusting the hair’s surface pH and promoting cuticle alignment, which increases light reflection without relying on heavy silicones. Because it’s pre-activated, the treatment targets the outermost layer of the strand to produce measurable shine gains immediately after rinsing.

• Citric acid helps close and smooth the cuticle for better reflectivity.
• Hydrogen peroxide assists in the glossing activation at a molecular level.
• Apricot oil adds lightweight nourishment, avoiding a weighed-down feel.

Can I use this on permanently colored or naturally pigmented hair?

Yes — the product was designed for both permanently colored hair and natural hair seeking added gloss and conditioning. It’s especially effective after color services or when you want to refresh vibrancy between salon visits, and pairs best with the Acidic Color Gloss shampoo and conditioner.

• Safe for use on permanent color and color-treated strands.
• Works equally well on natural hair to enhance surface shine.
• Recommended to follow with Acidic Color Gloss conditioner for best results.

How long do the shine and conditioning benefits last?

When used as part of the Acidic Color Gloss system, the treatment helps maintain a glass-like finish for days, with consumer testing indicating a significant increase in shine versus untreated, unwashed color-treated hair. Results depend on hair porosity and routine, but users typically enjoy improved gloss for up to several days after application.

• Provides visibly increased shine compared to unwashed color-treated hair.
• Delivers lasting surface smoothness for up to three days in system tests.
• Best longevity when combined with the matching shampoo and conditioner.

How do I apply the Redken Glass Gloss Treatment at home?

Application is quick and straightforward: apply to towel-dried, clean hair, distribute evenly, leave on for the recommended time, then rinse thoroughly. This rinse-out gloss is intended as a professional-grade, at-home step to refresh shine between salon gloss services.

• Use after shampooing with Acidic Color Gloss shampoo for optimal pH balance.
• Work through mid-lengths to ends; follow timing instructions on the bottle.
• Rinse out completely and follow with Acidic Color Gloss conditioner if desired.

Who is this for: Redken Acidic Color Gloss Glass Gloss Treatment is targeted at people with color-treated or glossed hair who want a salon-quality shine boost at home, plus those seeking a lightweight conditioning step that smooths the cuticle. It’s a good match for clients who use professional color services, anyone wanting to refresh vibrancy between appointments, and those who prefer a rinse-out gloss rather than a long-term color process. Avoid use if you’re following specific scalp or hair treatments that prohibit pH-altering products; consult your stylist when in doubt.
