Boost your locks with the Redken Cerafill Defy Shampoo for Normal to Thin Hair; an effective cleansing formula designed to visibly thicken hair, while offering a deep cleanse. Invigorating locks with a ginger mint fragrance, the shampoo is ideal for normal to thin hair types and is suitable for color-treated hair. Enriched with Zinc PCA, the gentle shampoo is able to strengthen the fiber and discourage breakages, as well as reducing DHT. The cleanser eliminates excess sebum and follicle-clogging impurities from the hair and scalp, leaving hair ultra-clean, shiny and visibly fuller.
