How Often Should You Change Your Shaving Razor? Dermatologists Answer

How Often Should You Change Your Shaving Razor? Dermatologists Answer

Why Do You Need To Change Your Shaving Razor Blades?

Most reusable shaving razors come with detachable heads known as cartridges. These cartridges hold the razor blades and require frequent changing. Here are the reasons why.

  1. Greater Risk of Cuts & Ingrown Hairs

This is a very crucial risk for more reasons than one. Cuts and nicks can lead to an unpleasant experience while shaving. Ingrown hairs also become more common when using old shaving razor blades, as they do not cut the hairs properly. There are several risks associated with nicks and cuts you can get while shaving that are discussed in the following points.

  1. Increased Risk of Infections

Old razor blades have bacterial buildup on them. This can happen due to several reasons, the most common of which is moisture and dead skin cell buildup on the razor blades. When you’re using an old razor for women, if you get a cut, the risk of infections skyrocket. Bacterial growth can increase your risk of breakouts, post-shave inflammation, and infections significantly if you’re using old razor blades.

  1. Tetanus Risk Due To Rusted Blades

Razor blades are made of stainless steel, but using them beyond their recommended use under suboptimal conditions, such as exposure to moisture, can lead to rusted blades. Any cut you receive while shaving using a rusty body razor can increase your risk of tetanus. This is a serious medical risk, and the reason brands always provide the recommended usage information on their packaging to prevent any medical complications due to rusted blades.

  1. Performance Degradation of The Razor

Last but not least, over time, the razor stops performing optimally. New blades of a high-quality razor are able to offer clean shave with only one pass when you’re using the right technique. Old razor blades will require multiple passes, and even cause irritation on your skin due to the additional friction. The performance degradation along with all the other reasons listed above is why you should always change your body razor blades as recommended.

Dermatologists Speak on How Often You Should Change Your Shaving Razor Blades

The American Academy of Dermatology states that you should throw away your razor cartridges or disposable razors every five to seven shaves. This is considered the rule of thumb by most professionals. The primary reason quoted for this change is to prevent irritation and a risk of razor burns. 


Other medical professionals have also echoed the thumb rule of American Academy of Dermatology. Dr Jessie Cheung a board certified dermatologist in the US also stated that razor blades should be changed every five to seven shaves. Dr Cheung, also stated that there are several other important factors that you should consider to determine just how quickly you should change your razor blades.

Reasons That Determine How Frequently You Need To Change Your Shaving Razor Blades


  • Hair Thickness: If you’re a person with thick hair, you may require more frequent blade changes.


  • Razor Storage: If your razor is left in the shower with water dripping from it, it can lead to quicker degradation of the shaving razor blades.


  • Hair Amount: If you are trying to shave a significant amount of hair every time, it can lead to quicker blade degradation. In such cases, it is advised to trim the hair lengths using scissors first and then use the razor to get a clean shave without overworking the razor.

How Do You Know When To Change Razor Blades?

The reasons listed above can require you to change your razor blades, even before the five to seven shaves that are recommended by dermatologists. So, how do you understand when you need to change your razor for women? Here are the signs that you can look for.


  • The razor won’t easily glide over your skin anymore

  • You won’t get a close shave on a single pass anymore

  • There will be signs of rust on the blade

  • You may get more ingrown hairs
