Give your hair an intensive boost with REF Stockholm’s hair mask – a deep-conditioning treatment that hydrates, strengthens and adds shine without weighing hair down. Begin with Shampoo, follow with the Hair Mask, and finish with Conditioner for a silky, glossy finish. Build your full routine with a Hair Mask for Dry Hair or Hair Mask for Coloured Hair, and add a Leave-In Conditioner for long-lasting softness.
