What Is a Shower Cap Used For?
Many people might think a shower cap only keeps your hair dry while taking a shower. But there are many ways a cap can be used:
- Hair conditioners and masks: The cap keeps your hair in place while the product does its magic. As you’re generally out of the shower at this time, it’ll also keep your clothes dry and clean.
- Protects your hairstyle: When styling your hair in the morning for an evening date, a shower cap will keep your hairstyle longer.
- Wear while sleeping: Protecting your hair at night avoids morning hair mess. It also limits the amount of hair damage while sleeping.
- Hair color: If you’re dying your hair, you need a shower cap. Without one, your clothes and surroundings could get permanently stained.
- While cleaning: Tidying up and washing a home can release huge amounts of dust, mold, and other unwanted debris or bacteria. Wearing a shower cap while cleaning should keep your hair clean and dirt-free.
Features to Look For
When selecting your next shower cap, here are important elements worth looking into:
A waterproof cap is essential. Without this, your hair will simply get wet, defeating the purpose of the cap. PVC, EVA, and double-layered products are typically the best at repelling water (1).
If you aren’t planning on purchasing a single-use shower cap, you’ll need to wash it. Some of them can be machine-washed, while other products need to be cleaned by hand. If hand-washing isn’t your favorite pastime, double-check the care label before you buy.
As we mentioned, some models can only be used once. Others, however, will last as long as the material itself does. While reusable caps are more eco-friendly, disposable products won’t need to be washed after a hair treatment or dye.
Mold is a common issue with shower caps usage, so look for a mold-resistant material, and ensure it dries fully between each use. Also, the elastic surrounding the head is usually the first part to give up, so ensure that it’s sturdy, thick, and high-quality.
The Right Size
A tight cap will be uncomfortable and may even cut circulation to your head, leaving unpleasant marks on the skin. Too loose, and it’ll let the water inside, or even fall off.
Many manufacturers display the diameter and how far a cap can stretch. Take your head’s measurements and compare them. Consider both the size of your head, but also all the amount of hair you have to fit in.
If you’re unsure, some brands come with an adjustable strap to allow the perfect fit.
Choosing the Right Design
If you’re opting for the single-use type, then design might not be the most important factor. But if you’re planning on keeping it long-term, choose a design you like. Luckily, many creative, luxurious, and colorful options are available.
The Best Shower Caps of 2021
Choosing the top 10 shower caps from the countless options available wasn’t an easy task. To find the best of the best, we dug deep and looked at features, quality, materials, user reviews, and expert opinion.

On top of that, this model is made of high-quality vinyl — EVA — which is less carcinogenic than regular plastic (2). Besides looking after your health, the manufacturer made sure that the material dries quickly, preventing mildew from growing.

The inner layer is composed of waterproof EVA, keeping water and moisture away. These caps aren’t just cute; moms also seem thrilled about their waterproof ability.
A few recurrent complaints mention the product’s small size. While it accommodates most children up to five years old, it may not be comfortable for older kids. To ensure proper sizing, measure your child’s head; the cap’s opening is 5.1 inches.

Made of both nylon and PEVA, this shower cap is designed to last (3). Not only is the cap waterproof, but it’s made of microbe-resistant components to prevent mildew from developing. In addition, when it’s time to get cleaned, the cap is machine washable.

Used while showering, you won’t only keep your hair dry, but you’ll also wash it at the same time. This is a great choice when traveling or when there’s no access to water.
If you tend to be sensitive to unknown body and hair products, this cap shouldn’t trigger allergies or skin reactions. It’s non-sensitizing, hypoallergenic, and helps keep a balanced pH. In addition, it doesn’t contain alcohol, lanolin or latex (4)!

This set comes with 120 shower caps; even if you use one a day, they should last you for at least four months.
Quality is still a critical factor in keeping your hair dry during that single-use. The caps are made of durable plastic material to prevent moisture from getting in.
Although they may seem thinner than other brands, they shouldn’t tear. The cap can even be stretched up to 17 inches, fitting most adults’ heads. However, they do tend to be too loose on kids.
They’re easy to carry and pack while traveling since they’re thin and compact. They aren’t much larger than a pen when folded, either.
- No washing needed.
- Enough caps for months.
- Durable plastic.
- Not environmentally friendly.
8. Betty Dain Socialite Collection Terry Lined Cap
Typically, shower caps with plastic inner lining aren’t comfortable to wear at night. They create a sauna environment, making the head sweaty and the hair moist. The Betty Dain cap is composed of nylon on the outer side, and cotton terry on the inside. This makes it suitable for both night and shower use.
Cotton terry material is known for its water absorption properties (5). It retains more moisture than other fabrics, which is a perk both while showering and sleeping.
Although the cap is mold and mildew resistant, we recommend letting it dry fully to prevent odors from forming. When necessary, put it in your drier for a thorough wash.
- Made of cotton terry material.
- Versatile use.
- Available in various designs.
- Mildew resistant.
- Elastic can be a little light.
9. Kitsch Luxury Shower Cap for Women
The Kitsch shower cap has black and white stripes, giving you an elegant look even while showering. If you’re looking for a high-quality, trendy cap, consider this one. The cute design includes a front ribbon and an elastic towards the neck for a snug fit.
Users seem thrilled with the durability of the product; some of them have been using it for years. The shower cap is 100 percent waterproof since it’s made of polyester, and keeps water away from the hair. It’s designed to accommodate all hair lengths, even waist-length locks.
While other models stretch over time, reviewers are delighted that the cap doesn’t deform with regular use. It’s recommended to tie your hair at the back of the head, towards the center. When fixed above the head, the cap might not fit properly.
Some users, however, mention that this model is a little too small, and the lining too tight for their liking.
- Classy style.
- 100 percent waterproof.
- Fits all hair lengths.
- Hand-wash only.
10. TURBELLA Luxury Shower Cap for Women
This model is the Rolls Royce of shower caps. Available at a higher price point, you likely won’t find someone else wearing it.
The cap shouldn’t let water in since it’s designed to be airtight. The three breathable fabric layers keep moisture level low, avoiding mildew. The breathability rate reaches 20,000 MVTR (moisture vapor transmission rate), which is exceptional when compared to other products.
The material also makes the cap extremely comfortable to wear and can be cleaned using a washer. The edges are made with an anti-slip and adjustable band — 18 to 25 inches wide — making the cap suitable for large and small heads. As needed, adapt the strap to your head size.
It’s designed to fit all hair types and lengths since it’s room and tall — 21 inches in diameter and 10.75 inches in height.
Last but not least, this model comes with a touch of luxury placed over the forehead, a Swarovski Crystal. It also comes in a cute but luxurious matching box, making a perfect gift.
- Adjustable size.
- Includes a Swarovski crystal.
- Made of breathable fabric.
- Comes with a gift box.
- Not as durable as claimed.
The best shower caps are a fun item to purchase. Choices are many, and designs can get really creative. A good place to start is to determine if you need a disposable or reusable product.
Then consider the size of your head and how much space you need to tuck your hair in. If you have very thick or long hair, it might be best to choose a large or extra-large cap with an adjustable string. If you don’t have access to water but still want to keep your hair clean and dry, shampoo caps might be what you need.
Finally, assess how you’ll be using it. Do you strictly need it while showering, or are you planning to sleep with it? Caps made exclusively of inner and outer plastic layers can get very uncomfortable when left overnight.
