If you’ve ever wondered “how long do razor blades last?” you’re not alone. At Smartshave, we get this question all the time. The simple answer is that most blades should be changed after 5–10 shaves, but the exact timing depends on your shaving routine, hair type, and skin sensitivity.
How Long Do Razor Blades Last?
On average, a blade will give you around a week of daily shaves before it begins to dull. If you shave every other day, you might stretch that to two or even three weeks. However, pushing a blade too far can cause irritation, cuts, and an uneven finish — which is why we recommend replacing your blades regularly.

Signs It’s Time to Replace Your Blade
Not sure when to change? Watch for these tell-tale signs:
- Tugging or pulling at your stubble
- Increased nicks or razor burn
- Blades that look dull, rusty, or clogged
If you notice any of these, it’s time for a fresh blade.
Factors That Affect Blade Life
- Hair type: Coarse or thick stubble will blunt blades faster.
- Shaving frequency: Daily shavers need replacements more often.
- Skin sensitivity: If your skin is prone to irritation, change blades sooner.
How to Make Razor Blades Last Longer
A few simple steps can extend the life of your blades:
- Rinse thoroughly after every shave
- Shake off water and store your razor in a dry spot (not the shower)
- Use a good shaving cream or gel with aloe vera and vitamin E to protect your skin
