After colouring, your hair’s pH can rise temporarily and cuticles may open more, which can cause colour fading and dullness. Redken developed this sulphate-free shampoo for coloured hair with an acidic pH (5.0–5.6), matching the natural pH of hair and scalp. In hair science, a slightly acidic environment is often linked to smoother cuticles and more shine, although effects vary per person and depend on overall hair condition.

Arginine and other amino acids in the formula are well-known conditioning ingredients that help make hair surface feel smoother. Your hair often feels softer and looks more even. According to Redken, coloured hair keeps its vibrancySi up to 32 washes; this is a brand claim based on Redken’s internal tests, not independent scientific research.

Yes, this shampoo contains no classic sulphates like SLS or SLES. Redken explicitly calls it sulphate-free, which matches the ingredient list. It does contain Sodium C14-16 Olefin Sulfonate, an anionic cleanser that cleans quite effectively. Combined with milder agents like Cocamidopropyl Betaine, this generally provides effective yet gentle cleansing for most users. If you have very sensitive or dry scalp, a strong cleansing ingredient can feel a bit drying, so observe how your skin reacts. For many with coloured hair, the formula is mild enough for daily or frequent use.

That depends on how your hair reacts to conditioning ingredients. For fine, normally coloured hair, this shampoo often works well: hair feels smoother and looks shinier without feeling heavy. The formula includes Amodimethicone and other caring polymers that create a thin, smooth layer on hair to enhance shine and manageability. Some users with very fine or quickly oily hair might find it feels heavier over time, especially if using the matching conditioner. In that case, apply conditioner only to ends and rinse thoroughly. The shampoo itself usually causes no issues for fine coloured hair.

Acidic Color Gloss focuses on shine and colour care for coloured hair in good condition. Acidic Bonding Concentrate is aimed at hair damaged by bleaching, heat, or frequent colouring. That line targets hair structure repair. If you have healthy coloured hair and want to maintain shine, Acidic Color Gloss is your pick. For porous, fragile, or overprocessed hair, check out the Acidic Bonding Concentrate Shampoo as an alternative.

What sets Acidic Color Gloss apart from many other colour-protecting shampoos is the mix of acidic pH and shine focus. While some shampoos mainly protect pigment, this formula also works to make hair surface as smooth as possible, enhancing shine visually. Compared to Kérastase Chroma Absolu, users often feel Acidic Color Gloss is gentler and smoother. Compared to cheaper drugstore options, the difference lies in the pH profile and the combination of caring polymers. If you have balayage or a Manente colour and want daily shampoo use that keeps hair silky soft and vibrant, this is a strong choice in its category.
