Redken Acidic Bonding Concentrate Shampoo

What real owners actually say

The overwhelming consensus from users is genuinely enthusiastic — this is one of those rare products where people sound *emotional* about their shampoo. Bleached and colour-treated hair types are the biggest winners here: users with platinum blonde, lightened, and chemically damaged hair repeatedly describe their hair as 'clean,' 'frizz-free,' 'shiny,' and 'transformed.' One bleached blonde user said they 'couldn't be happier' with how their hair feels. Another with fine platinum hair reported unprecedented shine and volume. The creamy texture gets a lot of love — people enjoy the sensory experience of washing with it. Several users specifically mention being able to stretch washes to 3–4 days, which for anyone with oily roots is a genuine game-changer. Perhaps the most telling signal: multiple users switched from Olaplex — the dominant bond-repair prestige brand — to Redken ABC and openly prefer it. One user said Olaplex gave 'only minimal results' over three years, while Redken delivered visible improvement quickly. Another flatly stated 'no Olaplex and no K18 did what this did.' Stylists are apparently noticing too — one user's hairdresser was 'under shock' at the growth and condition. However, it's not universal love. One user found it 'not worth it' after buying based on a video review. The price is repeatedly acknowledged as high, even by fans. There's also the smell — one person described a 'strong acidy smell' they didn't enjoy. Users also note that for best results, you really need the full system (conditioner, mask, or treatment), which makes the already-premium price tag multiply. Fine hair users generally love it, but a couple mention that certain Redken lines (like All Soft) can weigh hair down over time, requiring occasional clarifying. The product seems to genuinely excel for: bleached/highlighted hair, chemically damaged hair, fine hair needing volume, and anyone wanting to extend time between washes. Less certain for: people sensitive to strong scents, very tight budgets, or those expecting standalone miracles from just the shampoo.

The YouTube reviewers who actually tried it

YouTube reviewers across multiple channels — from the million-subscriber Blowout Professor to smaller creators like High Porosity Central and Blonde Amy — consistently validate what users are saying. The Blowout Professor, a respected hair science communicator, recommends the Redken ABC line prominently, and his audience credit his advice with transforming their hair. Lab Muffin Beauty Science (848K subs) dives into the ingredient science, explaining that the citric acid (an AHA) at 5th on the ingredient list serves a moisturising function rather than exfoliating — addressing the sun-protection warning on the label, which one commenter helpfully clarifies is a regulatory requirement for AHAs even in hair products, not a genuine scalp-damage risk. Reviewers testing on bleached and damaged hair show visible before-and-after improvements in smoothness, shine, and manageability. Blonde Amy's review demonstrates noticeably softer, healthier-looking hair post-use. The High Porosity Central channel — specifically focused on high-porosity hair types — gives the shampoo a strong recommendation, noting that hair even seemed to dry faster after use. A practical tip emerges from the comments on review videos: one user suggests washing first, applying the bonding treatment, then rinsing and conditioning — claiming this works better than the brand's 'pre-shampoo' instructions, which they suspect are simplified for marketing convenience. Georgia Bran's review raises the smell issue again, calling it a 'strong acidy smell' that might put some off. There's also an interesting budget alternative flagged: L'Oréal Ever Clear Bonding Shampoo and Conditioner is mentioned as a cheaper option from the same parent company, with one user claiming comparable quality. April Basi's review of the Curls variant suggests the curly-girl line exists as a separate formulation, which is worth knowing if you're choosing between them. Overall, the video evidence is remarkably consistent with user reports: effective for damaged and lightened hair, creamy and pleasant to use, expensive but worth it for the right hair type.
