Very Disappointed
2 days ago
I finished the entire bottle before writing this review because I wanted to give it a fair chance. Unfortunately, I did not notice any improvement in my hair. It cleaned my hair, but it performed no better than many regular shampoos that cost much less. My hair remained dry, frizzy, and difficult to manage, with no noticeable improvement in softness, shine, or overall condition. For a premium shampoo, I expected much better results. Unfortunately, I would not purchase it again.
No, I do not recommend this product.

We deeply appreciate you giving the product a true, fair chance by finishing the entire bottle. However, we are so sorry to hear that it did not deliver the transformative softness, moisture, and manageability you expect from a Redken formula.
When you invest in a routine, your hair should feel exceptional from root to tip. Since your hair needs deeper hydration and intense frizz control, we would love to help you find a richer, more tailored alternative. Please feel free to reach out to our customer care team or visit a partner salon so we can guide you to a formula that truly works for your hair type. 🤍

Healthy, Soft Hair Every Wash
3 days ago
I’ve been using the Redken Acidic Bonding Concentrate Shampoo, and it’s quickly become one of my favorites. It leaves my hair feeling incredibly soft, smooth, and healthy without weighing it down. My hair looks shinier, feels stronger, and is much easier to manage after every wash. I also love that it cleans well without making my hair feel dry, and the scent is fresh without being overpowering. I would definitely recommend this shampoo to anyone looking to repair damaged hair or simply keep their hair looking and feeling its best.
Yes, I recommend this product.

The best conditioner I’ve ever used
9 days ago
I have fine, brittle hair that dries out pretty easily on the ends. This conditioner absorbs right in and I don’t need much. My hair feels soft and moisturized without feeling heavy or greasy. I can easily brush my hair with little breakage and fall out. 10/10

Amazing Shampoo

I’ve been very happy with this shampoo. It cleans thoroughly without drying out my hair, and after a few washes my hair felt softer, smoother, and noticeably stronger. It also helps reduce frizz and leaves my hair looking healthier and shinier. A little goes a long way, so the bottle lasts a while. Great for damaged or color-treated hair.

This shampoo is “good”. It leaves my hair feeling very clean after, almost the same feeling you get when I occasionally use a clarifying shampoo. So much so that I thought I was totally drying out my hair. It hasn’t done that but it also doesn’t leave it feeling as soft as I hoped. I don’t hate it, it just wasn’t for me. I’ll keep trying to find the perfect match.
No, I do not recommend this product.

WHAT DOES ACIDIC BONDING SHAMPOO DO FOR YOUR HAIR?
The Redken Acidic Bonding Concentrate Shampoo is a bond strengthening shampoo designed to support damaged or colour‑treated hair. This sulfate‑free, ph balanced shampoo helps reinforce weakened bonds, resulting in smoother‑looking, more conditioned hair. The formula contains Citric Acid to help maintain an optimal pH level while delivering conditioning benefits for colour longevity. This acidic bonding shampoo also helps defend hair from the effects of colouring, hair styling and water exposure.
CAN YOU USE ACIDIC BONDING SHAMPOO EVERY DAY?
If you can use Redken Acidic Bonding Concentrate Shampoo everyday is up to your particular hair type and how frequently your scalp produces oil. For most colour-treated hair, using this formula two times a week is ideal for most hair types. This lets the natural oils re-coat each strand between use. Those with curly, coily or thick hair may prefer once‑weekly washing due to slower oil movement or our Acidic Bonding Curls Shampoo, designed to strengthen natural curls. Fine or straight hair may suit more frequent daily use or other hair care products for fine hair.
WHAT ARE PH‑BALANCED SHAMPOOS?
pH‑balanced shampoos are formulated to align with the natural pH range of the hair and scalp. Healthy hair typically sits between pH 4.5 and 5.5, but everyday factors such as water, colouring services and heat tools can push hair to a more alkaline state, affecting smoothness and manageability.
A pH-balanced shampoo and other Redken ABC hair care products help maintain this balance and supports the cuticle, contributing to shinier, smoother‑looking hair with reduced dryness or frizz. For colour‑treated hair, a low pH shampoo can also help maintain colour vibrancy and the appearance of stronger, well‑conditioned hair.
CAN YOU USE REDKEN ACIDIC BONDING CONCENTRATE PH-BALANCING SHAMPOO AS A LEAVE-IN TREATMENT?
No, this shampoo is designed to be rinsed out. It cleanses the scalp and hair while delivering strengthening benefits, which can then be followed with the Acidic Bonding Concentrate Leave-In Treatment for additional conditioning.
DO I NEED A PH-BALANCING SHAMPOO?
A pH‑balancing shampoo can be beneficial for all hair types, especially if your hair is coloured, dry or frequently exposed to heat tools. Redken offers a wide range of ph balanced shampoos tailored for different concerns, including our:
HOW IS ACIDIC BONDING CONCENTRATE DIFFERENT FROM OTHER BONDING PRODUCTS?
Our Acidic Bonding Concentrate Shampoo stands out for its use of Citric Acid, an alpha hydroxy acid that helps reinforce weakened hair bonds and support smoother‑looking, more conditioned hair. The low pH formula helps maintain optimal balance on the hair’s surface.
Unlike many bonding systems that are designed as additional steps or in-salon services, this low pH shampoo brings bonding care into a simple, everyday cleansing step suitable for all hair types and textures. It's the same bond repair shampoo Redken Global Ambassador Sabrina Carpenter swears by to maintain her signature blonde hair and bouncy bangs.
