make sure glycerin is not at the top of the ingredient lists. i do use products with glycerin in winter, but it is in middle/bottom part of list, and it also depends on the formulation, enough butters/oils in product to compensate i guess.

i use heavier leave ins in lower dews and most days i seal it.

i don't use protein treatments often, but i use them less often in lower dews, hair needs more moisture then.

i guess what it is is that hair loses moisture to the drier air, so we have to compensate for that. for sure my hair is happier in mid to high dews!
