Redken Acidic Bonding Concentrate 24/7 Treatment Serum

The Redken Acidic Bonding Concentrate 24/7 Night & Day Serum is a professional leave-in treatment that repairs damaged hair bonds. Formulated for fragile, brittle, and chemically treated hair that needs structural reinforcement.

What it is

A continuous bi-phase serum that works 24 hours a day to rebuild the hair fiber from within. The Acidic Bonding Concentrate technology works at an acidic pH to seal the cuticles and repair disulfide bonds damaged by coloring, bleaching, and heat treatments.

Who it's for

Suitable for medium to severely damaged hair, bleached hair, chemically treated hair, or hair frequently exposed to heat styling. Suitable for all hair types experiencing breakage, split ends, or loss of elasticity.

Benefits

Reduces breakage by 89% after just one application. Controls frizz for up to 72 hours, even in high humidity conditions. Strengthens the hair structure, increasing tensile strength. Restores natural shine without weighing hair down. Protects against heat up to 230°C during styling.

Ingredients and technology

Citric Acid: regulates pH to close cuticles and lock nutrients inside the hair shaft.

Polyglutamic Acid: a hydrating molecule that retains moisture 4 times more than hyaluronic acid, ensuring deep and long-lasting hydration.

Squalane: a plant-derived lipid that seals cuticles, prevents dehydration, and provides softness without greasy residue.

The concentrated formula penetrates the hair cortex to repair damaged bonds at a molecular level.

How to use

Apply 1-2 pumps to damp or dry hair, from mid-lengths to ends. Do not rinse. On wet hair after shampooing, distribute evenly before blow-drying. On dry hair, use as an anti-frizz treatment or before heat styling. Can be applied daily without buildup.

Result

Visibly stronger and more resilient hair from the first application. The fiber appears rebuilt, the lengths are sealed and protected. Hair maintains discipline and shine for 72 hours, even after subsequent washes. With continuous use, breakage progressively reduces, and hair quality improves.
