I'm hair mask-obsessed — and for good reason. My hair is prone to major frizz and dryness that sometimes only the richest and most moisturizing formulas can tame. When my hair is in dire need of a pick-me-up, my go-to move is to use a hair mask in lieu of conditioner, which usually gets the job done. But, admittedly, I never thought to supplement my shampoo and conditioner routine with a pre-treatment instead — that is, until I got my hands on the Redken Acidic Bonding Concentrate Intensive Treatment. Ahead, I break down everything you need to know about the reparative formula and what my experience was like using it.The Redken Acidic Bonding Concentrate Intensive Treatment FormulaThe star ingredients in this product are 14% citric acid, an alpha hydroxy acid (AHA) that helps strengthen bonds that have been weakened by factors like heat styling, getting your hair colored or environmental factors, and the brand’s Bonding Care Complex. Because AHA repairs the hair, the formula is considered an “intensive treatment” for damaged strands. And as someone who both colors and avidly straightens my hair, this product felt like it was formulated especially for me.
