We get it, we really do. Changing your razor can be a real pain. It's easy to forget you need to need to change it until you're already in the shower, and really by that point, no one wants to go to the hassle of hopping back out just to grab a razor. Don't even get us started on having to go to the store and buy refills that are expensive can be less than thrilling. We’ve been there too!

However, it’s SUPER important to change your razor and razor blades on a regular basis. You should always be using a fresh razor blade. If you’re using a dull blade that you have to press down super hard on your skin to get any hair off – you’re in for some trouble. The next question then is, how often should you change your razor blade?

Changing your razor made easy!


Do you ever get those weird red bumps after you shave that itch or irritate your skin? There are a few possible causes, including dry shaving instead of using shaving cream. But the most common culprit is a dull or damaged razor blade. When your razor blade gets dull, there is a greater risk for razor burn and skin irritation.

According to Jessica Krant, MD, MPH, board-certified dermatologist with the Laser & Skin Surgery Center of New York, says, “The duller the razor, the harder you have to press to make it do what you want. You get more collateral damage and more scraping of the skin.”

Those cuts also let in bacteria, viruses, yeast, and fungus — according to board-certified dermatologist Jeanie Chung Leddon, MD, Ph.D., co-founder of Boulder Valley Center for Dermatology.

Why would you run the risk of exposing yourself to bacteria when you can just regularly replace your razor blades and not have to worry about it?

Should You use more than one Razor? 

This is more of an issue for women then men because men typically only shave their face. However, if they are shaving other parts of their body (which is totally cool, no judgement from us) then they should definitely use more than one razor. 

For women, it can be a bit more unclear. Is it alright to use just one razor for your legs, armpits, and bikini area? The general understanding is that while using the same razor for all three regions may not pose a significant threat to your skin, you probably won't a get very close shave.


Sure, you can, but you might not want to. Why? Well, it could just be asking for trouble. When something gets wet, it leaves a lot more room for things to grow much more rapidly. This is especially true if your blades are starting to rust.

The best solution is to make sure that you rinse off leftover hair and any shaving cream after each use, and make sure to store your razor blade in a dry area, rather than the shower.

Shaving Tricks to Make Your Razor Last Longer

If you want you razor to last just a little more time, there are a few things you can do:

Use hot water when shaving. This will soften a hair follicle, making it easier to shave and less likely to dull or damage the blades. 

Rinse your razor off as you shave. After a couple swipes while shaving, rinse the blade under running water. This will help remove clogged hair or shaving cream in the blade, making it easier to use and less likely to get damaged. 

Don't try to shave dry. Use the proper shaving products like shaving cream for a smooth glide across your skin. 


Honestly, there isn’t a set time or number of uses before you should change the razor. However, you should be changing it after a few uses, before it gets exposed to bacteria. Your first sign of any rusting, a dull blade, tugging or nicking of the skin is your sign that your razor/razor head needs to be changed.

According to Whitney Bowe, MD, a dermatologist in NYC, “Women should get rid of their razor after a few uses, as it will have been exposed to bacteria.”

Basically, the more frequently you shave, the more frequently you should replace your razor blades. You’ll know when your blade is getting dull — pay attention to that and CHANGE YOUR RAZOR BLADES! Don’t ignore it and continue to use dull blades.
