Salon-Size Densifying Shampoo That Instantly Creates Fuller, Thicker-Looking Hair

Redken Acidic Grow Full System Densifying Shampoo in the generous 1L salon size is a pH-balanced, lightweight cleanser formulated to make thin and fine hair look and feel instantly fuller and thicker. Powered by Azelaic Acid and a 7% Densifying Care Complex, it coats the hair fibre to add visible thickness and volume while gently cleansing and rebalancing the scalp with hydration. Part of the complete Acidic Grow Full System, it works most effectively alongside the matching conditioner, serum and spray for a comprehensive approach to hair density. The 1L size is ideal for professional salon use or long-lasting home supply. Find it alongside other shampoos for thin hair in our full range.

Azelaic Acid and Densifying Care Complex for Instant Thickness and Volume

The 7% Densifying Care Complex coats each individual hair fibre to physically thicken the diameter of each strand — creating the appearance and feel of denser, fuller hair immediately after washing. Azelaic Acid contributes to the pH-balanced approach that rebalances and hydrates the scalp environment, supporting the conditions needed for healthy hair growth while the complex addresses the existing hair. The lightweight formula delivers all of this without any heaviness or residue — leaving thin hair feeling genuinely clean, soft and noticeably fuller.

Part of the Complete Redken Acidic Grow Full System

The densifying shampoo is the first step in the Acidic Grow Full System — a four-product routine of shampoo, conditioner, serum and spray that works together to balance the scalp, coat and thicken hair fibres and reduce breakage for a comprehensive approach to hair density. For the best volumising and densifying results, pair with the Redken Acidic Grow Full Densifying Conditioner and complete the system with the serum and spray.

How to Use Redken Acidic Grow Full Densifying Shampoo
