I would not buy this again
I thought this product would help my hair to be softer and less frizzy. I needed more hydration also.
Love it!
Received a free sample pack and love it! I will use it sparingly as it's expensive but it's made my hair so healthy in 3 washes.
Acidic Bonding Concentrate Shampoo
This shampoo was recommended by my hair stylist, the shampoo make my hair feels so soft and healthy, I'm glad I tried it.
I love this shampoo
I use this shampoo almost everyday because I work on a farm and washing hair is a must. I use with the conditioner sometimes but I usually rotate the 5 minute liquid mask or the matrix food for soft hair mask they are both worth every penny.
Not for me
I am halfway through the bottle of the Shampoo and Conditioner, my hair is shedding more than normal and I don´t notice any improvement.

I have coarse, PERM damaged hair that is dry and frizzy. Also color treated. I need help deciding which products would be best between this one, Acidic Curls or the Extreme. I'm interested in leave in treatments and styling products as well.
- Asked by Kamimi
- Official Answer By Redken - BEDealing with coarse, permed, color-treated, and dry hair is a lot to juggle, but we are here to help you find your ideal routine! While our Acidic Bonding Concentrate (ABC) line is fantastic for general bond repair and pH balancing, your permed strands might benefit most from combining the strength-building power of our Extreme line (like the Anti-Snap leave-in) to fortify damaged areas, paired with moisture-rich products from Acidic Bonding Curls to tame frizz and soften that coarse texture. We always recommend consulting a professional Redken stylist to feel your hair's elasticity and create the ultimate customized leave-in and styling cocktail for your unique needs!Was this answer helpful to you

- Q
How does this compare to protein shampoos?
- Asked by ML
- Official Answer By Redken - BEHi there! It is a great question! While both are designed to strengthen your hair, they actually work in two very different ways. Think of traditional protein shampoos like a temporary band-aid. When your hair is damaged, it loses its natural proteins, leaving tiny "gaps" in the outer surface. Protein shampoos work by filling in those gaps to make the hair feel stronger. However, if you use them too much, the protein can build up and actually make your hair feel stiff or dry. Our Acidic Bonding Concentrate (ABC) Shampoo goes a step deeper: It rebuilds from the inside out: Instead of just coating the surface, it uses an acidic bonding complex that penetrates deep inside the hair to rebuild weakened molecular bonds. It balances your pH: Hair loves acidity! ABC brings your hair back to its natural, healthy pH level. This seals your hair cuticle flat, which instantly locks in moisture, blocks color fade, and leaves your hair incredibly soft and shiny. No risk of "stiffness": Unlike protein, you can use ABC every single wash. It gives you the perfect balance of intense strength and luxurious softness without any heavy buildup. The short story: If your hair feels weak, dry, or color-damaged, ABC won't just patch up the damage—it will actually rebuild and rebalance your hair, leaving it 56% stronger and 11x smoother!Was this answer helpful to you
