Here’s how often you should replace the loofah in your shower, according to a dermatologist

Knowing when to replace your shampoo, conditioner and body wash is easy — when the bottle is empty, you know it’s time. But knowing when to replace your loofah? That can be a bit harder.

Quick Overview

Just like toothbrushes, loofahs need regular replacing to keep your hygiene in check. And chances are, your loofah is past due for a switch out.

“In general, aim to replace your shower loofah about every three to four weeks,” dermatologist Dr. Dusan Sajic tells In The Know. “But this timeframe can depend on the type of loofah you’re using. Natural loofahs tend to break down and become less effective more quickly than synthetic ones, so they might need to be replaced more frequently.”

Aside from use-related deterioration, there are other important reasons you should replace your loofah on this expert-recommended schedule.

“Loofahs can be a magnet for bacteria and other microbes, especially since they’re typically kept in the warm, moist environment of a bathroom,” Dr. Sajic says. “Replacing your loofah regularly reduces the chance of these bacteria causing infections or other skin problems.”

While replacing your loofah every month or so will help keep its effectiveness in check, there are simple ways to keep your scrubber in shape during its life to help maintain its benefits.

“It’s important to let your loofah dry out thoroughly between uses to minimize bacterial growth. Keeping it outside of the shower, where it can dry more completely, is a good idea,” Dr. Sajic says, adding, “Although most would find this self-explanatory, never share your loofah with others as it can spread skin conditions or infections.”

Picking out your perfect loofah is a highly personal thing, according to Dr. Sajic. More than shopping for a particular loofah type or brand name, the dermatologist says a quality loofah is one that works for your skin — especially if you have sensitive skin.

“For people with sensitive skin, a softer loofah or shower sponge might be a better option to avoid causing irritation,” Dr. Sajic says. “It’s always a good idea to look for products that have been tested and certified as safe and effective — or at the very least have great reviews online!”

If your loofah is in need of a switch, check out these top-rated options that will leave you squeaky clean — from traditional drugstore loofahs to all-natural luxe options.

This loofah is made with recycled materials.

$3 at Ulta

This loofah by EcoTools has a soft recycled netting, providing a more environmentally friendly take on plastic-based loofahs. The scrubber removes dead skin cells while lathering up for a gentle, all-over cleanse.

If you’re looking for something even more eco-friendly, try an all-natural loofah. Made from the dried fibrous skeleton of a loofah gourd, these natural scrubbers are what drugstore loofahs try to mimic. Why not give the real thing a whirl? Though they look scratchy, natural loofahs are surprisingly soft when wet.

These sponges were considered a luxury to the ancient Romans, according to the product description.

$23 at Anthropologie

A natural sea sponge makes a great loofah-like scrubber for your shower. Bacteria-resistant and lightly exfoliating, sea sponges are gentle on the skin and develop a rich lather. Plus, they are extremely eco-friendly.

It has a pocket for a bar or soap.

$15 at Kitsch

Instead of using a “traditional” bunched loofah, try an exfoliating washcloth made of the same material. This option by Kitsch has a built-in pocket for bar soap, helping you to lather up with ease. Its long length helps you scrub your back and other hard-to-reach areas for a complete clean.

For easy scrubbing, loofah pads are a great medium between a sponge and a loofah. Fitting right in your palm, this dual-sided loofah can sweep away dead skin cells and lather up your skin at the same time with its textured loofah side. The terry cloth side can be used as a washcloth for a gentler clean when you want a lighter hand.
