Redken Acidic Bonding Concentrate 24/7 Night & Day Serum (150ml) is Redken's first-ever bonding serum designed to provide 24/7 hair repair and protection for damaged hair. Tossing and turning in bed and rubbing against the pillow nightly can create friction that weakens the hair fibre, leading to breakage and damage.

This advanced formula harnesses the power of Citric Acid to penetrate seven layers deep, helping to strengthen hair and combat daily and nightly damage. Infused with a highly concentrated blend of Polyglutamic Acid and Squalane, this treatment magnetises to the hair, reinforcing its structure and preventing breakage while forming a long-lasting protective shield. Combat daily damage overnight and wake up to visibly healthier, stronger, 3x softer*, and 11x shinier**, with up to 89% less breakage*. This lightweight serum absorbs instantly into the hair without leaving residue, leaving hair smooth and soft after just one use. 92% agree hair looks and feels healthy after 24 hours***. Its luxurious fragrance combines Acidic Bonding Concentrate's signature citrus scent with soothing lavender notes, making it the perfect addition to both daytime and nighttime hair care routines.
