Fifteen matched shampoo and conditioner sets, every one of them $28 — sorted by what your hair actually needs rather than by scent. Rice water and rosemary for fine or thinning hair, castor and coconut oil for dry or damaged, tea tree and mint for oily scalps, purple toning for blonde and grey, and an ultra-sensitive option. Pick solid bars, which are bottle-free and rated for around 100 washes, or 12 fl oz bottles if you'd rather stick with liquid.
Free U.S. shipping over $35 — so two combos qualify, one on its own doesn't
