Redken Acidic Bonding Concentrate Shampoo & Conditioner Duo is a strengthening haircare set for damaged, over-processed hair.
This set includes 1 x Redken Acidic Bonding Concentrate Shampoo (300ml) and 1 x Redken Acidic Bonding Concentrate Conditioner (300ml). Together, they gently cleanse while helping to reinforce weakened bonds from colouring, bleaching, heat styling, or chemical treatments.
The shampoo creates a rich, creamy lather that feels cushioning on the scalp, while the conditioner leaves hair silky with a soft, smooth finish, not heavy or greasy. A light, clean salon-style scent makes hair feel freshly washed for longer.
Ideal for dry, fragile, or sensitised hair, this duo works beautifully for daily use or as a restoring routine after colour appointments. Hair feels easier to detangle, less snappy, and more manageable, with a sleek, nourished look.
