Designed to produce the same soft, glossy finish that the Princess of Wales is known for, this shampoo focuses on hydration and strength from the first wash. It gently cleanses while replenishing moisture, using plant-based proteins to help support strands and niacinamide to lock in hydration for long-lasting hair health. Ideal for normal-to-dry locks, the lightweight formula smooths, softens and detangles, boosting shine without ever feeling heavy.
