Redken Acidic Bonding Concentrate Leave-In Conditioner — Strengthening Leave-In for Damaged, Color-Treated Hair, Heat Protection t

Redken Acidic Bonding Concentrate Leave-In Conditioner is a lightweight, bond-building leave-in treatment that strengthens weakened hair, smooths split ends, and shields color and strands from heat damage.

Built for chemically treated, heat-styled, or naturally fragile hair, this professional-strength leave-in uses citric acid and Redken's Bonding Care Complex to target compromised bonds inside the fiber. It restores manageability and gloss while helping preserve salon color and providing protection from hot tools up to 450°F. Designed to be used after cleansing on damp hair, it layers into daily styling routines without weighing hair down.

How does this leave-in help repair damaged hair?

The formula works on a structural level to reinforce weak points inside each strand, reducing the look and feel of splitting and fraying. Citric acid helps rebalance hair pH, enabling the bonding complex to reconnect and fortify the cortex for improved elasticity.

• Bonding Care Complex targets weakened internal bonds for stronger strands
• Citric acid helps restore optimal hair pH to improve texture
• Leaves hair softer and less prone to breakage with repeated use

Will it protect my color and styling heat tools?

This leave-in includes ingredients that help lock in color vibrancy while forming a thermal barrier during styling. It’s formulated to reduce color fade from routine heat and environmental stress without dulling shine.

• Color-fade protection preserves salon color between appointments
• Heat protection up to 450°F for safer blow-drying and hot tools
• Lightweight finish avoids buildup that can mute color or weigh hair down

How do I use it in my daily routine?

After shampooing and conditioning, spray or apply the leave-in to clean, damp mid-lengths and ends—no rinsing required. Style as usual with a brush, blow-dryer, or heat tool; for best results use alongside the Acidic Bonding Concentrate shampoo and conditioner.

• Apply to damp hair, focusing on mid-lengths and ends
• Leave in—do not rinse—and style immediately or air dry
• Can be used daily or as needed to maintain strength and manageability

Is it suitable for my hair type and concerns?

The leave-in is formulated for a wide range of hair textures, especially hair that is color-treated, bleached, heat-damaged, or brittle. Its sulfate-free, vegan-friendly formulation is gentle while delivering targeted repair and smoothing benefits.

• Ideal for damaged, processed, or heat-stressed hair
• Works on fine to thick textures without heavy residue
• Safe for color-treated hair and daily styling routines
