Redken Duo Acidic Grow Full System Densifying Shampoo & Conditioner 2 x 300ml

Redken’s Duo Acidic Grow Full System Densifying Shampoo & Conditioner is a two-step haircare set designed to help thin, flat hair look fuller and feel instantly more nourished after one wash. The shampoo gently cleanses while delivering lightweight, root-lifting volume, and the conditioner follows through to support scalp hydration and help maintain density without weighing hair down.

Built around a 7% densifying care complex and azelaic acid, the range is made to leave hair with an improved, healthier-looking appearance and a more balanced scalp feel. Redken also positions the system to help reduce the look of breakage from brushing, so hair can appear thicker and sturdier over time. For best results, use the shampoo and conditioner together as part of the Acidic Grow Full System routine.
