From Wonder Valley, Sandalwood Yuzu shampoo: "Is it time for a new shampoo? Are you frequently washing your hair only to find it oily the next day? Maybe you’ve tried to find a cleaner formula but felt like it didn’t entirely wash out. Meet the Sandalwood Yuzu Shampoo; it is everything you’ve been looking for: performance, better ingredients, and naturally scented in a sustainable aluminum bottle." $36 for 300 ml at Smallflower, where the 1000 ml refill is $96 (and there's also a matching conditioner).
