Redken Acidic Bonding Concentrate 24/7 Night & Day Serum — Lightweight Repair & Anti‑Frizz (Lavender)

Redken Acidic Bonding Concentrate 24/7 Night & Day Serum is a lightweight leave-in treatment that rebuilds damaged hair bonds, reduces frizz, and delivers round‑the‑clock protection and hydration.

This concentrated serum targets weakened, chemically processed, or heat-stressed hair with a multi-tiered formula designed to repair and shield strands whether you use it before bed or as a daytime booster. It combines acidic bond-building chemistry with humectant and emollient actives to fortify fibers, smooth the cuticle, and help hair resist breakage and humidity for days.

How does this serum repair and strengthen damaged hair?

The formula uses citric acid to help restructure surface bonds, while polyglutamic acid and squalane deliver longer-lasting protection and moisture. Together these ingredients work at different levels of the hair fiber to reinforce weak points and reduce the appearance of split ends.

• Citric acid penetrates multiple hair layers to help re-link weakened bonds.
• Polyglutamic acid provides durable hydration and film-forming support.
• Squalane smooths and softens for improved manageability and shine.
• Designed for daily use to accumulate repair over repeated applications.

Will it control frizz and protect color-treated hair?

Yes—this serum offers humidity resistance and smoothing benefits that tame frizz for extended periods while helping preserve color vibrancy by minimizing mechanical and environmental stress. It creates a lighter protective layer than heavy oils, so color-treated hair stays manageable without looking weighed down.

• Provides extended humidity protection to reduce frizz.
• Non-greasy feel preserves style and color depth.
• Helps reduce daily breakage from brushing and heat styling.
• Lavender scent adds a calming aromatic finish.

How and when should I apply the 24/7 Night & Day Serum?

Apply to clean, damp or dry hair focusing on mid-lengths and ends—these areas benefit most from bond repair. Use more generously as an overnight treatment, or apply sparingly during the day to smooth flyaways and protect from styling stress.

• Dispense a small amount and warm between palms before applying.
• Work through mid-lengths and ends; avoid roots for a lightweight finish.
• Use nightly for accelerated repair or daily for continuous protection.
• Compatible with heat styling and other Redken styling products.

What results can I expect and how soon?

Visible smoothing and reduced frizz can appear after the first use, with progressive improvements in strength, texture, and split end appearance when used consistently. Results depend on hair condition and frequency of use, but most users notice softer, easier-to-manage hair within days.

• Initial smoothing and improved manageability after one application.
• Accumulated strengthening and protection with routine use.
• Helps lower breakage during daily styling and brushing.
• Lightweight finish maintains movement and shine.

Who is this for: This serum is aimed at anyone with processed, bleached, color-treated, heat-damaged, or generally weakened hair who wants a lightweight, leave-in solution to rebuild bonds, tame frizz, and protect strands day and night. It suits those seeking a non-greasy treatment that layers well with other products and delivers measurable smoothing and protection without heavy residue.
