How Often Should I Replace My Razor Blade?

Replace razor blades every 5-7 shaves, or about every 1-2 weeks with daily shaving. A dull blade causes more irritation than a sharp one.

Why This Matters

Frequently Asked Questions

Are more blades better?

Not necessarily. More blades can cause more irritation for sensitive skin. A sharp 2-3 blade razor often works as well.

Can I sharpen disposable razor blades?

Some people strop blades on denim to extend life slightly, but it's not a substitute for replacement.
