How to Use the Complete System

Step 1 - Shampoo: Apply to wet hair and gently massage the scalp. Emulsify until a light lather forms. Rinse thoroughly.

Step 2 - Conditioner: Apply an adequate amount to lengths and ends, avoiding the roots. Distribute evenly with fingers or a wide-tooth comb. Leave on for 2-3 minutes. Rinse with lukewarm water.

Pro Tip: For optimal results, complete the routine with the scalp rebalancing serum and the densifying volumizing root spray from the Acidic Grow Full line.

What to Expect

After the first applications, you will notice fuller hair, lifted at the roots, and with greater styling hold. With continued use, the hair fiber will be strengthened, volume will last longer, and the scalp will appear healthier and more balanced. Hair will be soft to the touch but with visible structure and lasting fullness.

Active Ingredients

Formula enriched with citric acid to rebalance scalp pH, a densifying complex that envelops each hair, increasing its perceived diameter, and light conditioning agents that nourish without weighing down. Professional Redken technology guarantees salon results at home.
