Anyone whose hair has been weakened by lightening, colour, chemical services or frequent heat styling, and who wants a daily shampoo that cleanses without sulfates. Redken formulates it for all hair types and textures, fine to coarse and straight to curly, and it is suitable for colour-treated hair.

It is a retail shampoo for home use, and the 1 L size is also practical for salons washing clients before and after chemical services.

Most shampoos for damaged hair focus on moisture alone. This one is built around Redken's acidic bonding approach: citric acid and a concentrated Bonding Care Complex work on weakened bonds at the cleansing step, and the acidic pH helps smooth the cuticle and protect colour. It gives processed hair a sulfate-free wash that fits straight into the rest of the Acidic Bonding Concentrate regimen, from the conditioner to the 5-Min Liquid Mask and the 24/7 serum.

1. Apply to wet hair and massage into a rich lather.
2. Rinse thoroughly.
3. Follow with Acidic Bonding Concentrate Conditioner or the Acidic Bonding Concentrate 5-Min Liquid Mask.

Pros:

• Sulfate-free surfactants clean processed hair without the stripped feel of a harsher shampoo
• Citric acid and the Bonding Care Complex start the bond-care routine at the wash step instead of relying only on a mask
• Acidic, pH-balancing formula helps colour-treated hair keep its vibrancy
• Available in a 1 L size that lowers the cost per wash

Cons:

• Contains dimethicone and amodimethicone, which some very fine hair types find a little heavy with repeated use
• Best results in Redken's testing come with the matching conditioner, so it works best as part of the system
• Contains added fragrance
