How Often Should You Replace Razor Blades?

Razor blades don’t last forever—no matter how sharp they feel. Knowing when to replace your razor blade is key to getting a clean shave without cuts, tugging, or skin irritation.

But how often should you really change it?

Let’s break it down.

General Rule of Thumb

Most people should replace their razor blade after 5 to 10 shaves. But this depends on several factors, including your hair type, how often you shave, and the quality of your blade.

Signs It's Time to Change Your Blade

If you're not counting shaves, here are some clear signs it’s time to swap out your razor blade:

Tugging or pulling instead of gliding smoothly

Razor burn or irritation after shaving

Redness or bumps you didn’t usually get

Dull feeling when you run it over your skin

You have to go over the same area multiple times

How Often Should You Replace Based on Use?

Daily shaver? Replace every week

Shave 2-3 times a week? Replace every 2–3 weeks

Occasional shaver? You might get a month or more, but still watch for dullness

If you're using a 6-layer razor, like those in our One-Year Shaving Kit, you might notice it lasts longer than standard blades—but it's still important to stay consistent.

Other Factors That Matter

Coarse hair wears blades faster

Not rinsing properly shortens blade life

Leaving it wet leads to rust or dullness

Using quality blades (like stainless steel ones) makes a big difference

Why It Matters

Using dull blades leads to more than just a rough shave. It increases your risk of:

Ingrown hairs

Razor bumps

Infection

Uneven skin texture

Fresh blades help protect your skin and give you a cleaner, more enjoyable shaving experience.
