I have to use the no scent stuff from the store but I've been able to make my own powder detergent from a recipe online. Just don't use Fels Naptha for the soap in the recipe if you are sensitive. It's really irritating and the scent lingers pretty strong in the clothes. My favorite soap to use is the Dr. Bronners bar, even the scented ones (my fav is rose). The scents are gentle.
