Product details:Finding the middle ground between healthy and happy tresses, the Medium Hair Shampoo Refill (946ml) cleanses deeply, hydrates and summons shine. Laying the foundation for stronger locks, this formula is infused with hydrolysed keratin (AKA the ideal pairing for heat-damaged hair) and kumquat fruit extract, which helps to return tired tresses to their former, glossy glory. Dehydrated strands dulling your shine? A moisturising blend of babassu and coconut oils will bring hair bright up to date. Fans of OUAI's Mercer Street fragrance will be pleased to hear that it makes an appearance here too: think zesty orange and Italian lemon happily married with floral notes of peony, magnolia, and jasmine. A complete refresh for your strands and senses, we're obsessed. OUAI Medium Hair Shampoo Refill 946ml
