Redken Acidic Bonding Concentrate Leave-In Conditioner — 150ml lightweight bond-building, heat & color protection

Redken Acidic Bonding Concentrate Leave-In Conditioner is a lightweight, citric-acid leave-in that rebuilds weakened hair bonds, smooths strands, and helps protect color and heat-styled hair.

This concentrated leave-in treatment is step 3 of Redken’s bond-building system, formulated to improve hair strength after chemical services, environmental stress, and thermal styling. It combines a bonding care complex with citric acid to deliver visible smoothing, reduced breakage, and color protection while remaining gentle enough for color-treated hair. A little product goes a long way: the creamy, concentrated formula coats fibers effectively without weighing hair down.

How quickly will I see improvements in damaged hair?

Many users notice smoother texture and reduced flyaways after the first application because the formula seals and coats strands to improve manageability. Continued use as part of a strengthening routine maximizes bond repair and longevity of results.

• Immediate smoothing and easier detangling after one use
• Progressive reduction in breakage with repeated use
• Best results when combined with the other steps in Redken’s bonding system

Can this product protect hair from heat tools and color fade?

The leave-in includes heat protection to help shield strands up to high styling temperatures while citric acid helps maintain the acidic pH that protects color fidelity. It’s formulated to be color-safe and to reduce color fade when used as directed.

• Thermal protection suitable for styling up to 450°F
• Acidic pH helps seal the cuticle and preserve salon color
• Lightweight finish won’t strip or dull color-treated hair

How much should I use and how do I apply it?

A small amount delivers strong results—start with a dime-sized portion and add more for thicker or longer hair. Apply to towel-dried hair from mid-lengths to ends, comb through to distribute, and style as usual; no rinsing required.

• Begin with a dime-sized amount for short to medium hair
• Increase quantity based on density and length
• Use on damp hair, then blow-dry or air-dry for best effect

What types of damage does it address?

The formula targets multiple sources of hair compromise—chemical processing, heat, sun, and mechanical wear—by reinforcing weakened bonds and delivering concentrated conditioning. It’s designed for a wide range of damage patterns, from split ends to overall fragility.

• Repairs and reinforces bonds weakened by chemical services
• Reduces visible split ends and minimizes breakage
• Hydrates and smooths hair without weighing it down

Who is this for: Redken Acidic Bonding Concentrate Leave-In Conditioner is suited for anyone with dry, chemically processed, heat-stressed, or fragile hair seeking a professional-strength leave-in that rebuilds bonds, improves manageability, and helps preserve color. It works well for fine to coarse textures because the concentrated, creamy formula is efficient—use small amounts for finer hair and slightly more for thicker or highly damaged lengths.
