I am so picky when it comes to deodorant, and have never found my favorite kind abroad. I typically travel with a full size tube when I'll be gone for a long time, but this technique is better for shorter trips. It's also a great way to customize the scent of your deodorant. Just buy an unscented stick and add your own essential oils or fragrance for a custom scent. Want to eliminate chemicals from your deodorant? Check out this chemical-free recipe from Scratch Mommy.
