Review Coming Soon
Our editors are currently testing Acidic Bonding Concentrate Intensive Treatment by Redken. Check back soon for our full review with ingredient analysis, pros and cons, and our expert verdict.
Salon/prosumer pre-shampoo bonding treatment using a citric-acid-based 'Bonding Care Complex' (~7%) that seals the cuticle and restores hair's pH — a different mechanism from Olaplex's disulfide-bond-relinking maleate chemistry, but named alongside Olaplex and K18 as one of the 'big three' at-home bond-repair technologies. UK retail (LookFantastic) lists it as 'Acidic Bonding Concentrate Intensive Pre-Treatment Bond Repair for Damaged Hair' at 190ml; the commonly cited US size/price of 5.07oz (150ml) at $30 could not be independently reconfirmed against a live US retailer this pass and should be treated as unconfirmed.
