My shower is a lot like my desk. As long as you don't open it, everything is fine. Just keep the curtain closed, because when you open it you will discover that I'm a hair care product junkie. I don't wait until I run out of shampoo or conditioner to buy more. My shower is stuffed full of them.I have them stacked on any ledge that will hold bottles.
I'm working on breaking my addiction to all those hair care products. I put everything away except one shampoo and one conditioner for the shower. I'll use those until they are empty, then I'll have plenty of choices for replacements. My shower looks so much nicer without all the clutter of too many bottles. It will also be much easier to clean without all the bottles to move and wipe under. Marking the products so I can easily identify them will save me some frustration when I'm in a hurry. This might even save me some money too, I won't need to buy shampoo for quite a while.
