I use only one for my body and hair. I wring out my hair while in the shower, towel off my body and then wrap my wet hair in the same towel. I use the hair dryer to dry my "nooks and crannies"

I live in an apartment, so I don't have the space to hang multiple towels to dry, and throwing a damp towel in the laundry hamper is disgusting. I also don't have my own washer and dryer so I need to be economical with how many towels I have on the go.
