I've been using Green Goo solid deodorant for a couple years now. I tried several different brands, but love that GG comes in a familiar stick form, so no getting my fingers sticky applying it with hands. But most importantly, it works! It handled my postpartum/hormonal changes with no problem, and stands up to workouts. I do sometimes reapply towards the end of the day, but as I have no concern about harmful ingredients, a quick second application doesn't bother me. I love not worrying about BO while using a totally natural product. I've used both the old formula (baking soda) and new formula (arrow root) and both work well. Thankful for a great product I can trust!
