But first, some science

Before we go on to tell you how to use Redken’s Acidic Concentrate backbar system, let’s look at some of the science that’s gone into this powerful concentrated system. If you have clients who like to know the details, this section will help you answer their questions!

The first thing to know is the formula upon which all of Redken’s products are based:


This formula basically sums up the science which underpins Redken’s Acidic Concentrate backbar system.

Acidic Concentrates is a 3-step backbar service and it really is as easy as 1, 2, 3; offering a professional, concentrated solution to support healthy hair in 3 key areas: protein, moisture, & pH balance. When used together, Acidic Concentrate Backbar service can visibly reduce the appearance of surface damage in a single treatment! 

How to use Redken’s Acidic Concentrates Backbar System

The first thing you’ll need to do is assess your client’s need for protein and/or moisture.

1. Assess hair damage

There are a few quick ways you can do this:

  • Take a strand of hair between two fingers and gently pull either end. Healthy, undamaged hair will stretch to around one-third of its original length. If the hair snaps then it will be suffering from protein damage. If the hair stretches, but doesn’t return to its original length, it is suffering from dryness.
  • Gently take an inch wide section of hair between two fingers and gently pull your fingers down the hair to the ends. As you’re pulling your fingers down the hair, concentrate on the texture and feel of the hair. If you can feel an uneven surface with kinks and sections that snap off under tension, then the hair is damaged.

Once you’ve assessed the extent of the dryness and/or damage to your client’s hair, it’s time to set up the treatment.

2. Set up the treatment

Depending on how badly damaged or dry your client’s hair is, you can use the Redken Acidic Amino Concentrate and Redken Acidic Moisture Concentrate in various ratios. This means you can provide a completely customisable treatment to help transform your client’s hair.

Apply the Acidic Protein Amino Concentrate to help strengthen and repair the hair, layer with the Acidic Moisture Concentrate to replenish the hair’s moisture and leave it feeling ultra-soft and silky, and finally finish with the Acidic pH sealer to achieve a smooth finish and long-lasting results.

As an added benefit, this whole treatment is very quick which makes it ideal for both time-poor clients and busy stylists!

3. Treat in 3 steps

Let’s quickly re-cap the process.

Step 1

Assess your client’s hair. If it’s particularly dry or damaged, make a note of this for the next step.

Step 2

Apply up to 15ml of the Acidic Protein Amino Concentrate to help strengthen and repair. Then layer with up to 15ml of the Acidic Moisture Concentrate which will replenish the hair’s moisture. Leave on for 5 minutes.

You can vary the ratios of these two concentrates depending on how much moisturising or repair is necessary. Please note though – the total formula of the two concentrates should not exceed 30ml.

Step 3

Complete the treatment with 10-15 pumps of the Acidic pH sealer to help balance the pH levels in the hair and seal the cuticle for a smooth finish and long-lasting results. Leave on for 1 minute and then rinse out and style.

Redken's Acidic Moisture Concentrate is ideal for moisturising very dry hair.
