When you are lathered up and ready to shave, the last thing you want to do is drag a dull razor across your face. Not only do worn-out razor blades prevent the close, clean shave you’re after, but they cause painful and ugly razor burn. It’s important to change your razor blades often enough to ensure it doesn’t irritate your skin, or worse, cause cuts, nicks, ingrown hairs, and infections. Not sure how often you should change your razor blades? Here are all the details to keep your razors sharp and your face smooth.
How often you should change your razor blades
According to the American Academy of Dermatologists, you should change your razor blades or throw away disposable razors after every five to seven shaves. High-quality razor blades should last five to seven shaves if you take care of them properly and keep them clean. However, cheaper disposable razors may wear out sooner.

Moreover, a razor that has an accumulation of gunk that can’t be rinsed away should be immediately discarded, as this causes nicks and infections by dragging unevenly across your skin and introducing harbored bacteria into your pores.
Factors that affect how frequently you’ll need to swap blades
While the general rule of thumb is to replace razor blades every five to seven shaves, there are four primary factors that influence the longevity of the blades.
The quality of the razor blades
Most replaceable razor blade cartridges are good for five to seven shaves, but if you’re using a cheap disposable razor, such as one that might be offered in a mid-tier hotel bathroom, expect to ditch it sooner. In general, you get what you pay for. The quality almost always affects the longevity of the razor blades and how often you should change them.
One of the first signs that cheaper razor blades are worn out and need to be replaced is the lubricating gel strips appear dried up or patchy, even when you wet the razor. These gel strips contain lubricating moisturizers to help the blades maintain consistent contact with your face and glide smoothly over it, which are important for preventing painful razor burns and accidental nicks and cuts.
The thickness and density of your hair
The thickness and density of your hair affect the lifespan of the razor blades. In most cases, the thicker and denser your hair, the sooner you’ll need to replace your blade because it wears out faster. Even if you have one but not the other—thick but soft hair or sparse but thick hair—the blades will likely wear out faster than someone with thin and soft hair.
The surface area you’re shaving
The more surface area you’re clearing with each shave, the faster your razor blades will wear out. If you were just
How well you clean your razor
How you care for your razor influences how often you should change the blades for better or worse. You should always use a lubricant, such as
Rinsing the blades after each swipe when you shave helps prevent buildup and dead skin cells between blades. After
Failing to clean razor blades will cause bacteria and debris to build up between the blades, which blunts the blades. Store your razor in a dry area — not on a sink or in the shower — to prolong the life of the razor blades. Lastly, for hygienic purposes and to make your razor blades last longer, use a separate razor for your face from one used on coarse body hair.
How often to change razor blades on an electric shaver
If you’re an electric grooming tool kind of guy, you certainly won’t need to replace your razor blades as frequently, but the foils and blades on electric razors do wear out and require replacement. The materials used to make electric razor blades are more durable than those used for disposable razors, so they often last six months or so. Again, this depends on how often you shave, the quality of the razor, the coarseness and density of your hair, the surface area you’re
If you shave every day, you may need to change the razor blades and foils every four months. You may also be able to get a year of use out of high-quality electric razor blades used only a couple of times per week. Heat and friction cause the blades to become dull, so wet
Electric razors with foils tend to last even longer, and may only need to be changed every 12-18 months if you take good care of the razor, shave with wet hair, and thoroughly clean the razor after every use.
