The Real Scoop: How Often Should You Wash?
We all know that feeling: stepping into the shower, grabbing the shampoo without a second thought – washing your hair has become second nature. But, as Dr. Anthony Rossi, dermatologist and member of the American Academy of Dermatology, points out, daily hair washing is actually far from ideal. So what’s the magic number to avoid damaging your locks?
The best frequency? Well, it’s not as one-size-fits-all as you might hope. In an interview with CNN, Dr. Rossi shed some light on the subject. Is it daily, every other day, or just once or twice a week? The answer isn’t unanimous – but there are some practical guidelines to help find what works for you.
Why Daily Washing Isn’t Your Hair’s Best Friend
« Some people think they need to wash their hair every day. They just can’t stand skipping a shampoo for too long because they feel like their scalp gets too greasy, » explains Dr. Anthony Rossi.
While the urge to keep things squeaky clean might seem harmless, washing too often isn’t actually recommended. The big issue? According to Dr. Rossi, frequent washing can dry out and dull your hair. Ouch.
He advises:
- For most people, washing your hair once or twice a week is enough.
- In some cases, even less is better! If you’ve undergone treatments—think bleaching, perms, or relaxers—that tend to dry out your hair, limiting washes to less than once a week is a good move to avoid brittle hair and split ends.
Hair Types, Lifestyles & The Goldilocks Principle
Frizzy, curly, straight—a lot depends on the type and texture of your hair, as well as your usual level of activity. Dr. Rossi highlights that people who exercise regularly don’t necessarily need to wash their hair after every workout. Unless you notice bacteria making itself at home or—no beating around the bush here—your scalp and hair start to smell.
« Thick and curly hair generally doesn’t need to be washed every day, or even every week, » notes the American Academy of Dermatology.
For those with curly or frizzy hair, washing too frequently can actually increase dryness or breakage. In short: different strokes for different folks (and follicles).
Dry Shampoo: Savior or Quick Fix?
Let’s address the elephant in the bathroom—dry shampoo. According to Dr. Rossi, most dry shampoos are considered safe for your hair. The catch? Don’t overdo it. As he puts it:
« If your hair is very oily, sure, dry shampoo works … to a point. But you still need to wash it. You don’t want that stuff building up on your scalp. »
And one last pro tip: if you’re fussing over clean hair with a dirty brush, you’re kind of missing the point. Dermatologist Dr. Nina Roos (in an interview with French magazine Femme Actuelle) recommends cleaning your hairbrush every 15 days—especially if it’s gathering dust. That’s right: pristine hair deserves a pristine brush!
Bottom line: impeccable hair hygiene is a happy medium between not too much and not too little. Your hair—and your scalp—will thank you.
