Redken Acidic Protein Amino Concentrate Hair Treatment is Redken’s most powerful backbar formula yet—engineered exclusively for professional use to target dry, damaged, and over-processed hair. Now improved with a creamier consistency for easier application, it’s expertly formulated to deliver high-impact strength and support protein balance during in-salon treatments.

Powered by a 12% blend of cationic and amino acids, this intensive treatment visibly reduces surface damage in a single use when combined with Redken’s Acidic Moisture Concentrate and pH Sealer. Suitable for colour-treated hair and ideal for layering within a personalised backbar routine, it reinforces weakened strands and helps prevent future breakage.
