For those that suffer from breakouts on their neck, back and butt regularly, there could be a simple shower trick that you can do to limit the amount of pimples on your body. While we can’t say firsthand whether it works or not (we haven’t tested it out just yet), it seems to be getting a lot of attention on Reddit, and here’s why.

One user posted that if you are having trouble with acne on your body, to try washing your hair and conditioning it before you wash your body in the shower. The post also says that making this simple swap has helped tremendously in the amount of bacne he sees.

We asked New York dermatologist Jessica Krant, MD, about the theory of washing your hair before your body and if the science behind it has any credibility. “I’m sure no formal studies have been done on the timing of hair washing and conditioning, but it sounds like a smart idea to me to wash your body after your hair is rinsed to remove any heavy conditioning agents that might contribute to acne like oils, fragrance or chemicals.”

Paramus, NJ, dermatologist Rebecca Baxt, MD, adds that those with long hair should always wash, condition and clip it up. “Rinse your hair off to the side if possible,” she advises. “This way, you don’t get the oils from your conditioner on your back.”

In the event that washing your hair first and your body second doesn’t do much of anything to clear up your breakouts, Dr. Baxt says you can always add a second layer of protection and wash in the shower with a benzoyl peroxide-based wash. “It’s helpful to treat and prevent back acne. And, it would be best to have benzoyl peroxide be the last thing you use in the shower on your back and then rinse it off.” She also says that some patients find it helpful to leave the wash on for a few minutes before rinsing clean.

And, once you step out of the shower, it’s best to apply an over-the-counter product that contains benzoyl peroxide or salicylic acid, too. “You can also ask your dermatologist about prescription options if needed,” says Dr. Krant.
