When you think of products you use in the shower, a shower cap is typically an afterthought, but you should never underestimate the usefulness of one. A shower cap is your secret weapon for helping maintain your hairstyle—a must-have for those who don’t like washing their hair every day. They do a great job taming frizz and blocking the humidity from messing up your hairstyle, making sure all that time and effort you put forward styling your hair doesn't go to waste.

Not to mention, some shower caps offer uses beyond the bath. A shower cap can protect your hair while you sleep or even be used to make hair conditioning treatments work better. More good news: These days, shower caps are just as stylish as they are functional, available in a mix of vibrant colors, prints, and textures to boot.

We rounded up the best shower caps out there that get the job done.
