What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Contains the brand's patented bond-building technology, which reviewers say genuinely helps repair hair weakened by bleach, highlights, or heat
- Sulfate-free and colour-safe formulation suits chemically treated hair
- Works well as a maintenance companion alongside the brand's in-shower treatment products, helping preserve repair results between treatments
Reviewers push back
- Multiple reviewers find it lacking in hydration — the shampoo's bond-repair focus appears to come at the cost of moisture delivery
- Described as heavy, which can make hair feel oily or dirty more quickly than a standard shampoo, shortening time between washes
- Bottles are small relative to the amount of product required per wash, especially for long or thick hair
A functional bond-repair shampoo that works best for chemically processed or heat-damaged hair, but reviewers largely agree it is a specialised tool rather than an everyday shampoo for everyone.
Professionals and enthusiast reviewers disagree on whether No. 4 is worth buying at all: one hairstylist-reviewer actively discourages it for most people in favour of No. 3 alone, while another hairstylist-reviewer still recommends it for the right candidate
