- Asked by Robin
- Official Answer By Redken - BEHi there! Thank you for your interest in our Acidic Bonding Concentrate Leave-In Treatment. This product can be used on its own with other shampoo and conditioner products if you'd prefer, but the maximum benefits and all of our claims are based on using each product line as a complete system.

- Q
How often can i hse this product? Is there a limit?
- Asked by Ali
- Official Answer By Redken - BEHI there! Thank you for reaching out about our Acidic Bonding Concentrate Leave-In Treatment for Hair Repair. Excellent question! The Acidic Bonding Concentrate Leave-In Treatment is designed for daily use, or whenever you wash and style your hair. There is no "limit" to how often you can apply it, as it is a highly concentrated, yet weightless formula that works to repair and protect your hair throughout the day. It’s a perfect step to include in your routine to ensure your hair stays nourished and protected against heat styling and humidity. However, since a little goes a long way, we recommend starting with a small amount and adjusting as needed based on your hair's length and thickness to maintain that soft, weightless finish.Was this answer helpful to you
- Q
Hi, can I use redken acidic bonding concentrate and living proof no frizz oil ?
- Asked by Ash
- Official Answer By Redken - BEHi there! Thank you for reaching out about our Acidic Bonding Concentrate Leave-In Treatment for Hair Repair. That is an excellent question! The short answer is yes, you can absolutely use the Redken Acidic Bonding Concentrate (ABC) Leave-In Treatment and the Living Proof No Frizz Oil together. In fact, they make a powerful duo for achieving a smooth, high-shine finish. Here is the best way to layer them for a professional "pop" of results: Foundation (Damp Hair): Apply the Redken ABC Leave-In first to clean, damp hair. This is your "bonding" step—it works internally to repair weakened bonds, provides 450°F heat protection, and balances your hair's pH. Sealing (Damp or Dry Hair): Follow with the Living Proof No Frizz Oil. You can apply a small amount to damp hair over the ABC treatment to lock in moisture, or use it on dry hair after styling to smooth down any remaining flyaways and add a boost of shine. Why they work well together: The Redken ABC focuses on repair and strength, while the Living Proof Oil focuses on blocking humidity and adding surface smoothness. By using both, you are getting the internal structural benefits from Redken and the external frizz-protection from Living Proof. Just remember to start with a small amount of each, especially if you have finer hair, to ensure your style stays lightweight and bouncy!Was this answer helpful to you
- Q
When does this one, if ever, going on sale? I thought shampoo and conditioners (related, Acidic Bonding) in the past years were the same as the other one on sale in the past. (All Soft, and others…)
- Asked by Kaitlin
- Official Answer By Redken - BEHi there! Thank you for reaching out about our Acidic Bonding Concentrate Leave-In Treatment for Hair Repair. While we cannot disclose specific future dates for sales, here is some helpful context regarding how the ABC line is treated compared to ranges like All Soft: Retailer Participation: Sales are often determined by our authorized retail partners (such as Ulta, Sephora, or professional salons). While classic lines like All Soft or Extreme are frequently part of "Jumbo" or "Liter" sales, the Acidic Bonding Concentrate line—being our most advanced, high-performance bonding technology—is sometimes included in different promotional tiers. Value Sets: One of the best ways to get the Leave-In Treatment at a better price point is to look for Value Sets or Holiday Bundles. These kits often include a full-size Leave-In along with the Shampoo and Conditioner for a significant overall saving compared to buying them individually. Newsletter Perks: We highly recommend signing up for the Redken newsletter or rewards programs at your favorite professional beauty retailer. They often provide early access to "Friends & Family" events where the entire brand, including the ABC range, may be discounted. Our Acidic Bonding Concentrate formula is highly concentrated, so a little bit of the Leave-In goes a long way—providing 56% less breakage and heat protection up to 450°F!Was this answer helpful to you

Love this stuff
Hair Type Very Curly Hair
I don't go without this stuff anymore. I love the way it smells and how it makes my hair feel whether I let it dry on its own or if I blow dry it. Best Leave in Conditioner that I've used in a long time
Love this leave in!
Hair Type Very Curly Hair
I am using this entire line and this leave in has done an amazing job of repairing my fried hair. My hair was so damaged I had lost all curl and it was desert dry and frizzy. Just a couple uses and you could see the difference. My hair is once again curly, soft, and way less dry!
I will buy this over and over again

For those of you looking for a product to tame the frizz in curly hair, I would definitely recommend this. You will notice the difference with the first yse.
Amazing for Bleached Hair

I love this stuff. I added blonde highlights a year ago and was straightening my hair often. This kept my hair intact, and my stylist was so proud that my hair was thriving between visits. I highly recommend for color-treated hair.
