How to Use

Step 1: Cleanse

Apply Redken Acidic Grow Full System Shampoo to wet hair. Gently massage into the scalp and hair to create a lather, then rinse thoroughly.

Step 2: Condition

Apply Redken Acidic Grow Full System Conditioner to freshly washed hair, concentrating on the mid-lengths and ends. Distribute evenly and rinse thoroughly.

Step 3: Strengthen & Hydrate

Spray Redken Acidic Grow Full System Scalp & Hair Serum directly onto the scalp and roots from approximately 2.5cm away. Gently massage into the scalp using your fingertips. Do not rinse.

Step 4: Densify & Style

Spray Redken Acidic Grow Full System Instant Densifying Spray onto clean, damp hair from approximately 15cm away. Comb through the mid-lengths and ends to distribute evenly, then blow-dry and style as desired.

Styling Tip: For extra bounce and fullness, blow-dry using a round brush, lifting hair away from the roots to maximise volume.
