Damaged hair is one of the most common hair concerns to manage. From breakage, to dryness and split ends, there are many ways that your hair can show signs of damage. Luckily, by choosing a strong haircare regimen that treats and restores the protein of your hair, you can strengthen your strands.
Damaged hair is caused by chemical treatments, heat styling, and environmental stressors, resulting in weak, brittle strands. Redken’s Acidic Bonding Concentrate (ABC) system repairs weakened bonds, rebalances hair pH, and restores strength and moisture for healthier, stronger hair. Redken’s Extreme Collection addresses various types of hair damage, provides moisture and conditioning benefits while fortifying the hair. No matter what type of hair damage you have, there’s an Extreme haircare range that can revive your hair and repair your hair damage.
WHAT CAUSES DAMAGED HAIR?
Understanding what causes hair damage is the first step to fixing it. The most common causes include:
According to Redken Artist Adina Doss @mastery_adinadoss, hair damage occurs when the hair has been compromised and the hair’s proteins are weakened. This can be caused by chemical services such as hair color or highlighting processes and mechanical services, like heat styling or blow drying.
“Damaged hair can look frayed and similar to a flyaway." says Redken Artist Julie Lahr @julie_lahr, "Sometimes you’ll begin to notice the damaged hair when split ends begin to appear.”

HOW TO REPAIR DAMAGED HAIR
Repairing damaged hair requires a consistent routine focused on rebuilding hair bonds, restoring moisture, and protecting strands from further harm.
1. Pre-Treat with Intensive Bond Repair: Begin your regimen 1-2 times a week with Redken’s Acidic Bonding Concentrate Intensive Treatment. This concentrated pre-shampoo formula penetrates deeply to repair broken bonds and prepare hair for cleansing and conditioning.
2. Cleanse Gently and Strengthen: Use Redken’s Acidic Bonding Concentrate Shampoo every wash. Its sulfate-free, bond-fortifying formula gently cleanses without stripping moisture, while rebalancing the hair’s pH to strengthen weakened areas. For added protein support,Redken Extreme Shampoo is an option to reinforce strands from root to tip.
3. Condition Deeply and Seal Bonds: Apply Acidic Bonding Concentrate Conditioner or Lightweight Liquid Conditioner (for fine hair) daily. These conditioners close the hair cuticle, improve smoothness, and lock in moisture. For more intense repair, substitute the conditioner once or twice weekly with the Acidic Bonding Concentrate 5-Minute Liquid Mask, which delivers ultra-hydration and fortifies hair bonds effectively.
4. Protect and Repair with Leave-In Treatments: Finish with Redken’s Acidic Bonding Concentrate Leave-In Treatment on damp hair. This multi-benefit product repairs bonds continuously, protects hair from heat (up to 232°C/450°F), controls frizz, and detangles strands for easier styling.
Alternatively, Redken Extreme Anti-Snap Leave-In offers 5-in-1 protection to reduce split ends and strengthen hair.5. Limit Heat and Styling Tool Use: Avoid frequent use of heat styling tools like flat irons, curling wands, and blow dryers. When heat styling is necessary, always use a heat protectant treatment to minimize damage. Give your hair regular breaks from styling to allow recovery.
6. Protect Hair from Environmental Damage and Mechanical Stress: Wear hats or scarves to shield hair from sun exposure and pollution. Use gentle hair handling techniques—avoid harsh brushing or towel drying—and opt for loose hairstyles to prevent unnecessary breakage.
7. Maintain Regular Professional Treatments: Enhance your at-home care by seeking professional bond-building treatments at salons. These treatments complement Redken’s ABC system by targeting internal damage with advanced technology and restoring lost proteins and moisture.
8. Sleep on Silk or Satin Pillowcases: Switching to silk or satin pillowcases reduces friction on hair while you sleep, minimizing breakage, frizz, and split ends. These smooth fabrics help maintain moisture and protect hair integrity for healthier strands over time.
ACIDIC BONDING CONCENTRATE

There are a lot of things that can damage your hair, including chemical treatments, friction, and the regular use of hot tools. While dealing with this damage isn’t fun, using the right products can noticeably improve how your hair looks and feels. And as far as products for damaged hair go, Redken’s Acidic Bonding Concentrate line-up can’t be beaten. The collection consists of five distinct products: A shampoo, two conditioners (one richer, one more lightweight for fine hair), a leave-in treatment and styling aid, an ultra-conditioning liquid mask, and a 24/7 day and night repairing serum.
The line is formulated for all hair types and textures, and provides an all-in-one solution to intensely condition, repair, and protect color-treated strands. Also worth noting is that the entire range is housed in recyclable plastic packaging, making it the perfect addition to your green beauty routine. And, Redken teamed up with The Braille Institute to add Braille instructions to the packaging, making the products more accessible to all consumers. That’s two points for the line right off the bat.
The Redken Acidic Bonding Concentrate system is formulated with citric acid, an alpha-hydroxy acid used in a variety of skincare products, and the brand’s Bonding Care complex. These ingredients work together to reinforce weakened bonds to help build your hair’s strength and resiliency. The acidic formulas defend against the damaging effects of hair coloring, styling tools, and even water while also helping to rebalance your mane’s natural pH levels for healthier-looking, stronger hair. In just one use, the complete system combats up to a full year of visible damage, reducing breakage by 56 percent, visibly reducing split ends by 82 percent, and leaving damaged hair up to 14 times smoother.
