"You want to treat with medications that treat the yeast and look for ingredients like zinc pyrithione," says Bhanusali. "I usually tell my patients to use a product like Dove Men+Care Derma+Care Scalp 2 in 1 Shampoo & Conditioner Dandruff Defense, $4.89, or Suave Anti Dandruff Itchy Scalp Relief 2-in-1, $3.48, as a body wash." It may sound counter-intuitive to use shampoo on your body — but it turns out that Malassezia, the yeast that causes fungal acne, is often the culprit for dandruff as well. Bhanusali adds that you should leave the shampoo on as a treatment for around five minutes before rinsing and continue for a few weeks. Then, once it's cleared up, you can add in the anti-dandruff shampoo every once in a while after particularly sweaty gym sessions.

Gohara adds that in addition to any prescriptions you might receive after consulting your dermatologist, a soothing body wash can also help. "Using gentle cleansers is key so the fire isn't stoked," she explains. "My favorite is the Dove White Beauty Bar, $1.29. It moisturizes and replaces skin-identical lipids as it cleans."
