Overview
An acidic, pH-balanced formula is what sets Redken Acidic Color Gloss Shampoo apart: it helps seal the hair cuticle to lock in shine while cleansing. The sulfate-free base washes gently to protect color from fading and dulling.
Colored hair loses gloss as the cuticle roughens, and an acidic cleanse helps flatten it back down. Expect the strongest shine only when paired with the Glass Gloss Treatment from the same line.
Who it's for
Color-treated hair that fades or turns dull quickly benefits from the cuticle-sealing wash. People with untreated, oily hair may prefer a stronger cleanser.
Pros and cons
- Acidic pH helps seal the cuticle
- Sulfate free, gentle cleanse
- Protects against color fading
- Adds salon-like shine
- Top shine claim needs the gloss treatment
- Gentle wash may not clear heavy buildup
Performance notes
A low pH tightens the cuticle layer, which smooths the surface so it reflects more light and holds dye molecules in longer. Without sulfates the cleanse is mild, so heavy styling products may need an occasional stronger wash.
