    deep clean without leaving my hair feeling like straw

    I paired the leave-in mask with their clarifying shampoo, and it has been a game-changer for my hair routine. It gives my scalp and strands a serious, or stripping away moisture. It completely removes all the product buildup and hard water minerals, which I think is why the leave-in mask works even better now. My hair feels completely refreshed, bouncy, and ready for repair!
