Switching between the two formulas as the weather shifts has been surprisingly seamless—my scalp stopped feeling greasy by mid-July, and the winter wash leaves my hair less static-y in dry indoor heat. The texture of the summer one is thinner, which makes it easy to work through wet hair fast.

The winter wash has made a noticeable difference in how my scalp feels when the air gets dry and cold—way less tight and flaky than last year. Switching between the two bottles as the weather shifts is oddly satisfying, and I've already seen less oil buildup on those sticky July days.

Switching from the summer bottle to the winter one as the weather cooled felt like finally giving my hair what it needed. The seasonal split makes so much sense once you notice how different your scalp behaves — my hair stays balanced without me having to over-wash.
