FREQUENTLY ASKED QUESTIONS

Answers to Your Frequently Asked Questions

 

Does blow‑drying damage hair?

Yes. Blow‑drying can contribute to dryness and rough‑feeling hair over time, especially when high heat is used without protection. To help minimise heat‑related stress, always apply a blow‑dry heat protectant or hair primer before styling. The Acidic Bonding Concentrate Leave‑In Treatment also works as a blow dry cream, helping support smoother, softer and better‑protected hair while you dry and style.

What causes split ends, and how can you get rid of or prevent them?

Split ends occur when the ends of the hair fibre weaken and fray. Common causes include heat styling, brushing, chemical services and environmental stress.

The only way to remove split ends is to trim them. Between cuts, you can improve how they look by using a hair treatment for split ends to help smooth and condition the ends. Steps that help support healthier‑looking lengths include using hair creams and lotions limiting excessive heat, detangling gently and adding split hair treatments to keep the ends feeling softer and more manageable.

How often should I use Redken's leave-in treatment on damaged hair?

You can use the Redken leave in treatment after every wash. Apply to damp hair before styling to help support smoother, more manageable and better-protected lengths. Its lightweight texture makes it suitable for daily use, including on colour‑treated hair.

How do you best apply Redken's ABC leave-in hair treatment as a hair smoothing treatment?

Apply the Acidic Bonding Concentrate Leave‑In Treatment to clean, damp hair. Work it through mid‑lengths and ends, then comb to detangle before styling. Using it on damp hair helps smooth the cuticle and supports the ABC leave‑in treatment as a hair treatment for smooth hair.

How long should I leave the Acidic Bonding Concentrate Leave-In Treatment in?

The Acidic Bonding Concentrate Leave-In Treatment is designed to stay in your hair until your next wash. Apply to clean, damp hair, leave in and style as usual, there’s no need to rinse. This lightweight formula can also be left on overnight as a leave in conditioner.

Can I skip conditioner and use Redken ABC Leave-in Treatment as a leave-in conditioner?

It's recommended to use both normal shampoo, conditioner and leave-in conditioner to achieve healthy, shiny and strong results, but you can also use the Redken Acidic Bonding Concentrate Leave‑In Treatment as a leave‑in conditioner.

It delivers conditioning, smoothing and heat‑protective benefits that help support stronger‑feeling, healthier‑looking hair, even on days you choose to skip your rinse‑out conditioner.

If your hair feels dry, coarse or prone to breakage, adding a leave‑in step is especially helpful. Use your ABC shampoo as usual, then apply the Redken ABC Leave‑In Treatment to damp hair to support softer, more manageable lengths.

For deeper overnight softness and enhanced conditioning on non‑wash days, try pairing it with the Acidic Bonding Concentrate 24/7 Night & Day Serum, a lightweight bonding serum designed for around‑the‑clock care

Is the Acidic Bonding Concentrate Leave-In Treatment suitable for colour‑treated hair?

Yes. It’s suitable for colour‑treated and chemically processed hair. The formula supports conditioned, smoother‑feeling lengths and helps maintain the appearance of your hair colour while caring for sensitised ends. It also works as a hair treatment for coloured hair, helping support softness and vibrancy during your styling routine.
