Redken Acidic Protein Amino Concentrate, 9% Cationic + Amino Acid, 3.4 fl oz

Redken Acidic Protein Amino Concentrate is a professional, salon-grade strengthening treatment formulated to repair, fortify, and reinforce weakened, damaged, and over-processed hair. Powered by a potent 9% blend of cationic proteins and amino acids, this targeted concentrate replenishes essential protein and helps rebuild hair from the inside out.

Designed for use both in professional salons and as an intensive at-home strengthening booster, this formula helps restore the structural integrity of chemically treated, over-styled, or breakage-prone hair. The acidic pH helps rebalance and protect the hair’s natural barrier, enhancing shine, softness, and manageability.

Why It Works

The combination of cationic proteins (which bond directly to damaged areas) and amino acids (building blocks of hair) makes this formula especially effective for strengthening weakened strands and restoring internal structure for healthier, more resilient hair.
