Redken Acidic Color Gloss (ACG) Treatment is a quick in-salon glossing service designed to give your hair intense, reflective shine while protecting and prolonging your colour. Using acidic, amino-acid-rich formulas, the treatment smooths the cuticle, deeply conditions, and leaves hair noticeably softer and more manageable—all without adding pigment. It's especially effective on colour-treated hair and fits easily as a 15-minute add-on to your cut, blow-dry, or colour appointment at our Handcross salon.
More information
What happens during the treatment
Your stylist will apply the Activated Glass Gloss Treatment to mid-lengths and ends after shampooing with the ACG system. The treatment is left on for around 5 minutes, then thoroughly rinsed. The whole process takes around 15 minutes and can be added to any service.
- No colour deposited — ACG enhances existing colour and vibrancy by smoothing the cuticle and adding reflective shine
- Hair appears up to 76% shinier with a glass-like finish that lasts several days
- Suitable for all hair types, from straight to coily, and especially recommended for professionally colour-treated hair
Who it's for
ACG is ideal if you want to boost shine, protect your colour investment, and improve manageability between full colour appointments. It's particularly helpful for:
- Colour-treated hair that's looking dull or lacks vibrancy
- Hair that's been lightened, highlighted, or toned and needs extra conditioning
- Anyone seeking smoother, less frizzy hair with improved detangling
- Clients who want healthier-looking, more polished results without a long appointment
Even virgin hair benefits from the shine boost, though the most dramatic improvements are usually seen on frequently coloured or chemically treated hair.
Maintaining your results
Results are temporary and will gradually diminish with washing, heat styling, and environmental exposure. To keep your gloss finish looking its best:
- Use colour-safe, pH-balanced shampoos and conditioners (Redken's ACG home system is designed to complement the treatment)
- Apply a heat-protection leave-in before styling to preserve shine and prevent damage
- Avoid harsh clarifying shampoos and minimise high-heat tools where possible
- Repeat the treatment regularly or as recommended by your stylist—many clients book it alongside their colour refresh
Our team in Handcross will talk you through a tailored aftercare plan that fits your routine and keeps your hair looking salon-fresh for longer.
