I like lavender because lavender is a really calming fragrance, so lavender witch hazel is just another bit of lavender into the steamers. If you can't find it, an unscented witch hazel will work. Just make sure that you don't choose an alcohol-free witch hazel. You need the alcohol in the witch hazel to help the dry mixture start clumping. If you use water, the steamers won't solidify as well and will be a crumbly mess.
