Choosing razor blades and shaving heads: how to avoid buying the wrong ones

Choosing new razor blades and shaving heads might seem straightforward. Yet many people order a refill that won’t fit their handle, a shaving head for the wrong series or a multipack that turns out to be poor value per item. Terms such as ‘extra close’, ‘long-lasting’ and ‘for sensitive skin’ only mean something if you check the product specifications behind them.

This guide helps men and women in the Netherlands choose the right razor blade refills, replacement shaving heads and accessories for Gillette, Braun, Philips and Xiaomi systems.

Three common pitfalls when choosing razor blades and shaving heads

1. Confusing a brand name with compatibility

Not every Gillette refill fits every Gillette handle. Gillette Fusion5, ProGlide, Mach3, Venus and GilletteLabs use different systems, so always check the exact product range. Packaging that simply says ‘Gillette razor blades’ doesn’t give you enough information.

For electric systems, the model number is even more important. A Braun shaving head for Series 3 won’t automatically fit a Series 5 or Series 7 device. The same applies to a Philips shaving head: the SH50/50 is designed for Philips 5000 Series models, while a Bodygroom replacement foil uses a different connection.

2. Looking only at the number of items

A pack of 20 or 28 blades might look like good value, but check the blade type and expected lifespan too. According to Gillette’s product information, a Fusion5 refill offers up to 20 shaves, based on shaving three times a week. This is a brand claim, not a guarantee for every user. Hair growth, shaving frequency, skin preparation and cleaning all affect how long the blades actually last.

3. Taking lubrication strips and comfort claims too literally

A lubricating strip, microfins or a gel cushion can help the razor glide while you shave. However, the experience varies from person to person. If you’re sensitive to certain substances, check the ingredients and instructions for use too. Claims about skin comfort or reduced irritation should be treated as manufacturer information, not medical promises.

Important specifications to check

1. Compatibility and model number

Before buying, look for:

  • the brand and product series;
  • the exact model number of your shaver;
  • the connection or cassette shape;
  • whether it’s described as ‘genuine’ or ‘compatible’;
  • the number of items in the pack.

The model number is usually on the back or underside of an electric shaver, or in its manual. Make a note of it before ordering replacement shaving heads.

2. Type of shaving system

Know the difference between:

  • Manual refills: such as Gillette Fusion5, ProGlide, Mach3 and Venus;
  • Electric shaving heads: such as Braun cassettes or Philips rotary shaving heads;
  • Trimmer foils: for example, for a Xiaomi UniBlade or Philips Bodygroom;
  • Cleaning cartridges: maintenance products for compatible Braun SmartCare Centers.

A cleaning cartridge doesn’t replace a shaving head. It’s a maintenance accessory designed for a specific cleaning or charging station.

3. Materials, care and replacement intervals

Check the stated material, cleaning method and recommended replacement interval. Product information for various Braun and Philips heads, for example, recommends replacing them approximately every 12 to 18 months. This is the manufacturer’s recommendation; replace them sooner if the foil is bent, the blades are damaged, the shaver becomes inconsistent or shaving feels noticeably less comfortable.

Only rinse parts if the manual and product specifications say it’s safe to do so. A device that isn’t designed for wet use must not be used in or near water.

Frequently asked questions about razor blades and shaving heads

How do I know which replacement shaving head I need?

Make a note of your device’s model number and compare it with the compatibility list on the product page. For Braun, check the Series and cassette number, such as 54B, 52S or 74S. For Philips, check the Series and designation, including SH50/50. Don’t order based only on a photo or brand name.

How often should I replace razor blades or shaving heads?

It depends on how often you use them and how worn they are. Gillette says some Fusion5 blades offer up to 20 shaves, while Braun recommends replacing several of its electric shaving heads approximately every 18 months and Philips recommends around every 12 months for the SH50/50. These are manufacturer recommendations. Replace them sooner if the blade pulls, the shave becomes less effective or any parts are damaged.

Do I need shaver accessories such as cleaning cartridges?

A cleaning cartridge is only needed if your shaver uses a compatible cleaning or SmartCare station. Check the manual and the station model. Only use cleaning fluid for its intended purpose, keep cartridges out of reach of children and follow your local disposal instructions.
