Buying replacement shaver heads and razor blades: how to find the right fit and avoid a costly mistake

A blunt razor blade, an electric shaver that tugs or a cleaning station without a cartridge can make shaving harder than it needs to be. But if you’re looking for replacement shaver heads and razor blades, you’ll quickly come across a wide range of options, with different model numbers, pack sizes and marketing claims. A low price means little if the part won’t fit your device.

So keep an eye out for these three common pitfalls:

  1. The wrong compatibility: a shaver head for Braun Series 5 won’t necessarily fit every Series 5 generation. The model number on the device or old cassette is what matters.
  2. A counterfeit presented as an original: words such as “premium” or “precision” don’t prove that a part comes from the brand itself.
  3. A large pack that doesn’t really save you money: a multipack is only practical if the blades fit your handle or shaver and you’ll use them within a reasonable time.

Which specifications should you check?

1. Brand, series and model number

Check the exact number before buying. Examples include Braun 32B, 52S, 54B, 74S, 83M and 96M, Philips SH50/50 and SH91/50, or Gillette Mach3. Even with an electric shaver, “Series 5” on its own may not be specific enough. Different generations can use different attachment mechanisms or foils.

That’s why a search for Braun replacement shaver head will often show a model number after the series name. If you’re looking to replace Philips shaver heads, check that the part is made for the right range, such as Philips 5000 or Philips 9000. For a manual system, check the handle: Gillette Mach3 refill blades fit Mach3 handles, while GilletteLabs uses its own system.

2. Part type and fitting

A shaver head, foil, cutter block and cleaning cartridge are not the same thing. A round Philips head fits differently from a Braun cassette. Look out for terms such as:

  • Shaving head or shaver head replacement for a complete electric shaver head;
  • Foil replacement for a replacement shaver foil;
  • Cutter and foil for a combination of foil and cutter block;
  • Refill blades for a manual shaving system;
  • Cleaning cartridge for a cleaning station.

Check how the part fits, too. Products such as the Braun 74S and 83M are described as click-fit. With the Philips SH91/50, you need to align the holders and retaining rings correctly. Always switch off the device and unplug it or disconnect the charger before replacing a part.

3. Pack size, material and replacement interval

Don’t just compare the price of each pack. Compare the price per shaver head or blade, too. Braun cassettes are often sold individually, while the Philips SH50/50 pack contains three shaver heads. Gillette Mach3 is available in packs of five or 25.

How often you need to replace a part depends on how often you use it, hair thickness, care and wear. The intervals given are guidelines from the product information, not a guarantee for every user. Braun recommends replacing various Series 3, 5, 7, 8 and 9 parts after around 18 months, according to the product descriptions. For the Philips SH50/50, the stated interval is around 12 months; for the SH91/50, it’s around two years. Replace the part sooner if the foil is damaged, the blade tugs or shaving becomes less comfortable.

For razor blades for sensitive skin, possible product features include a lubricating strip, rounded tips or a protective foil. How well they work varies from person to person. Treat brand claims about skin comfort or reduced irritation as claims made by the manufacturer, rather than guaranteed results.

Frequently asked questions about replacement shaver heads and razor blades

How do I know which shaver head fits my shaver?

Look for the model number on the device, packaging or instruction manual. Compare it with the model number on the product page, such as Braun 54B, 74S, 83M or 96M, and Philips SH50/50 or SH91/50. Don’t rely on the series name alone.

How often should I replace shaver heads?

It depends on use and wear. Product guidelines range from around 12 months for some Philips heads to around 18 months for various Braun cassettes. For the Philips SH91/50, the stated interval is around two years. Use these intervals to plan ahead, but replace the part sooner if the blade tugs, the foil is damaged or the blades look visibly blunt.

Do I always need original razor blades?

Original razor blades or shaver heads make it easier to find a clear match when you know the brand and model number. An alternative may cost less, but check compatibility, fitting and safety information especially carefully. Don’t use a part that’s loose, damaged or doesn’t fit properly.
