How should I catagorize my bathroom?

I am cleaning my bathroom and I want to organize all of my skincare products in catagories. I have my shower stuff in the shower, and the stuff I use everyday on a ledge above my sink, but I have 9 bins, 3 droors, and 2 under the sink cabinet areas to work with for storing the rest of my stuff. I stack the bins I have on a shelf thing, and I dont know if I should put all my body things in one bin, all my face stuff in another bin, and all my hair stuff in another bin etc., but then there are so many different types of body things like body lotion, body scrubs, body wash ect., so should I put all the scrubs in one bin, and all the lotions in another bin too, but then should those bins also include the face scrubs and face lotions? You can see how this can get so confusing! So can I please get some help? If you are a skincare junkie who has as many products as I do you know what I'm talking about. If anyone can give me some catagories, that would be great. Thanks :)
