# Shampoo for color-treated hair

Source: HiveTried, https://hivetried.com/beauty/shampoo/for-color-treated-hair/
Category: Beauty > Shampoo. Updated 2026-10-08. Based on 256 counted first-hand reports from Ulta and Sephora shopper reviews, Nov 2019 to Aug 2026.

**Question:** Which shampoo keeps color-treated hair from fading?

**Short answer:** Pureology Nanoworks Gold Hydrating Shampoo has the best record: 8 of 8 reviewers said it kept their color from fading or going brassy, but that is a small group because many reviews talk about scent and softness and say nothing about color. Redken Color Extend Magnetics Shampoo follows at 11 of 12 with more reviewers behind it. Most reviewers weighed in on OUAI Detox Clarifying Shampoo, and it has the weakest record here at 8 of 18.

**What stands out:** Pureology holds two of the five spots. OUAI Detox Clarifying Shampoo reads very differently by store: 4 of 5 at Ulta against 4 of 13 at Sephora.
