Redken Acidic Bonding Curls Silicone-Free Shampoo
by Redken · hair_care
Editor's Take
Sulfate-free amino acid surfactants meet Salicylic Acid and Citric Acid in a curl-focused shampoo that actually treats the scalp while sealing the cuticle.
Four-pillar formula scores
- Efficacy: 7.8 / 10
- Modern Tech: 7.5 / 10
- Clean Beauty: 4.5 / 10
- Sustainability: 5.8 / 10
The Verdict
This is a legitimately modern curl shampoo that delivers on both structural repair and scalp clarity. The acidic pH system (Citric Acid plus Glycine) seals the cuticle while Salicylic Acid clears buildup, a rare pairing in the curl category. Efficacy is well aligned for curly hair needing both bond support and scalp health, and the sulfate-free surfactant base is gentler than most professional lines. Clean score sits at mid-range due to ethoxylated surfactants like PPG-5-Ceteth-20 and undisclosed fragrance, but the technology is current and the actives are well-chosen. Worth it for curly hair dealing with both damage and scalp congestion.
