How Often Should You Replace Electric Razor Blades (And How!)

Every shaver should include maintenance as part of their routine, especially when using an electric razor. This includes replacing the electric razor’s blades, but how often should you replace them?

The blades on most electric razors should be replaced every 12 to 18 months. The frequency can vary depending on how thick or coarse your hair is, so if you notice your razor is no longer effective, it is probably time to replace the blade. When they are not replaced, the blades will become dull resulting in decreased performance and irritation.

Read on to find out if electric razors get dull, how often you need to replace electric razor blades and electric shaver foils, and how long they typically last. Finally, we’ll go into detail about the best way to replace electric razor blades. 

Do electric razors get dull?

Just like any other shaving razor, electric razors dull over time.

Once you notice a decrease in performance or any irritation, it is time to replace the blades. Factors that may contribute to dulling the razor include:

  • Frequency of use – If you shave 3 to 5 times per week, the blades will become dull more quickly.
  • Coarseness of hair – Hair that is more course will dull the blades more quickly than fine hair.
  • Thickness of hair – Hair that is thicker will dull the blades more quickly than thin or sparse hair.

On average, a shaver should expect to replace the blades on their electric razor every 12 to 18 months, if not sooner. By replacing the blades, shavers will maintain the closeness they come to expect when shaving. 

A common misconception is that when the electric razor slips in performance, it is time to replace it. Rather, it is simply a sign of wear and tear. Rather than shelling out money on a brand new electric razor, buying replacement blades will do the trick.

Can you sharpen electric razor blades and foils?

When the blades get dull they should be replaced, but can you sharpen the existing ones?

Electric razor blades can often be sharpened, but foils cannot. The best way to sharpen an electric razor blade is by attaching a sharpening head to the blade.

Foils cannot be sharpened because of how small the spaces are in between the oscillating blades. This makes it near impossible to attach a sharpening head. 

Sharpening electric razor blades

Follow these steps to sharpen an electric razor blade with a sharpening head:

  1. Unplug the razor and turn it off.
  2. Remove the frame that holds the blades.
  3. Remove each blade.
  4. Remove screens around each blade.
  5. Attach and fasten sharpening head in place of screens.
  6. Reassemble and turn on to sharpen blades.
  7. Once complete, break down razor to reinstall screens.
  8. Reassemble once screens are installed.

Keep in mind that you should not use sandpaper to try and sharpen them. It will snag on the blades.

How often do you need to replace electric razor blades?

To maintain the performance and safety of your electric razor, they should be replaced every so often.

Every brand is different. Some might call for blades to be replaced in a short time frame than the average. Some razor blades might last for 2 years. It all depends on how often they are used, and the type of hair you have. 

While performance is important, not replacing your electric razor blades can also pose a health risk. If they are not sharp enough, they might cause increased irritation, redness, or ingrown hairs.

How often do you need to replace electric shaver foils?

Electric shaver foils are a bit different than electric razor blades. Should a shaver apply the same time frame to replace them?

As a rule, electric shaver foils should be replaced every 12 to 18 months depending on the brand. Like electric shaver blades, they become dull over time. Shaver foils might become duller faster depending on use frequency and thickness, or coarseness, of hair. To lengthen the life of the foils, be sure to follow routine maintenance practices. 

The life of an electric shaver foil depends on the manufacturer. However, it is always recommended to replace the shaver foils with brand-specific replacement foils. If you try to replace them with a different brand, you may encounter issues. 

As always, regular maintenance of your electric shaver foils will lengthen the foils’ lifespan. By doing daily cleanings and weekly deep cleanings, a shaver can generally expect the shaver foils to last the estimated time frame. 

It should be noted that while you can sharpen electric razor blades, electric shaver foils cannot be sharpened.

How long do electric shavers last?

A quality electric shaver can last up to 5 years. High-quality electric shavers are known to last up to 7 years, while you may only get about 3 out of a lower quality one. With such a long lifespan of an electric shaver, it is important to realize that when its performance slips, it is often only a sign the blades need replacing. 

It is crucial to also understand that an electric shaver’s lifespan is connected to the amount of maintenance you perform on it. By properly maintaining the electric shaver, you are ensuring that it has the capability to last for 3 to 7 years. Without proper maintenance, an electric shaver only has an outside chance of lasting that long.
