3 Dermatologists Weigh In on If You Should Use a Loofah

If you must use a loofah, Dr. Jaliman suggests you clean them frequently. "If you want to use them, then place them in diluted bleach once a week [to kill the bacteria]," she said.

Dr. Nussbaum advises that you rinse your loofah well and make sure it dries completely between uses. She also recommends that you replace them frequently. "I recommend getting a new one every three weeks or so." she said. "Also — and this is important — never share them."

If you want to continue to use your current loofah, Dr. Nussbaum has a few tips to kill the bacteria harboring in it. "Wash the loofah in very hot water at least once a week," she said. "I recommend running it through the dishwasher, dropping it in boiling water for five to seven minutes, or microwaving it for around 30 seconds weekly."
