JustK Purifying Anti-Dandruff Keratin Shampoo 300ml is a sulphate-free anti-dandruff shampoo designed to reduce visible flakes, soothe itchy scalps and deeply cleanse buildup without stripping moisture. Infused with keratin, rosemary and tea tree, this refreshing formula helps rebalance the scalp while leaving hair soft, clean and revitalised.
Formulated with Piroctone Olamine to help target dandruff-causing microbes, this purifying shampoo works from root to tip to eliminate flakes and calm irritation. Tea Tree and Rosemary oils deliver a cooling, fresh sensation, while Panthenol and conditioning agents help maintain softness and manageability.
Keratin supports smoother, stronger-looking strands, helping reinforce the hair fibre and improve shine over time. The result is a clean, comfortable scalp and hair that feels healthy, light and flake-free.
