Disposable razors are for limited use. In general, they can last three to 10 shaves, but the best indicator it’s time to replace a disposable razor is when the blades become dull. When you’re ready for a new razor blade, you throw away the entire razor and grab a new one.

Due to their limited use, disposable razors are great for traveling and to have on hand for any house guests who might have forgotten their own razors at home. Many high-quality disposable razors are built similarly to reusable razors in that they have three to five razor blades — compared to just one or two — and an easy-to-grip handle for a better shave with less risk of nicks, cuts, razor burn and bumps.

The main difference between reusable and disposable razors is that reusable razors have a razor handle you keep with detachable blade cartridges you refill as needed. Reusable razor blades typically last five to 10 shaves; but, just like disposable razor blades, the best way to gauge when to replace a blade cartridge is dullness. Regardless of the type of razor you choose, if the blade starts to pull at your body hair or feel rough when gliding across your skin, it’s time for a replacement.

Reusable razors are great for anytime use. And, some reusable razors can even adapt if and when your shaving needs change, because different types of blade cartridge refills can fit the same razor handle. So, you can determine what type of blade works best for your body hair preference, whether that’s three or five blades, blades made specially for sensitive skin or blade cartridges with built-in shave gel. And, using a refillable handle is also better for the environment because you throw away less plastic.

Whether you prefer disposable or reusable, what’s most important is choosing a razor that helps you achieve your desired shaving results. Learn how you can build you own razor and see all the Venus shaving products available to make sure you get exactly what you need.
