Replacing a shaving head: how to choose the right replacement

You can often tell when a shaving head is worn out because your shave is less even, the shaver pulls at your hairs or you need to go over the same area more often. However, ordering a new electric shaving head without checking first isn’t always a good idea. A part may look as though it fits, but still not be compatible with your Braun, Philips, Remington or Xiaomi model.

The main pitfalls when replacing a shaving head are:

• Choosing the wrong model: a shaving head for a Philips 5000 Series shaver won’t necessarily fit every Philips shaver.
• Confusing a head, cassette and blades: some products replace the complete shaving head, while others include only the shaving blades or foil.
• Marketing claims without verifiable specifications: terms such as ‘close shave’, ‘comfortable’ or ‘long-lasting’ don’t tell you much without a model number, details of what’s in the pack and a replacement interval.

So, first check the model number on your device or in the manual. Then compare the part number, the number of items included and how the replacement shaving head attaches.

Which specifications should you check?

1. Model number and compatibility

The model number is the most important thing to check. Look for codes such as 74S, 96M, SH91/50, SH50/50, 52S or SPF300. A general description such as ‘men’s shaving head’ isn’t enough to confirm compatibility.

Check the product family:

• A Braun shaving head for Series 3, 5, 7, 8 or 9 isn’t interchangeable with the others.
• A Philips shaving head for the 5000 Series differs from one for the 9000 Series.
• A body groomer often uses a foil or trimmer replacement head, not a standard rotary shaving head.
• For a Xiaomi or Remington accessory, always check the exact name of your device.

2. What’s actually in the pack?

Check whether you’re buying a complete cassette, loose shaving blades, a foil or a complete trimmer head. This affects both the price and installation.

For example:

• According to the product information, the Braun Series 7 74S comes as one original replacement head.
• The Philips SH91/50 contains three replacement shaving heads, according to the product specifications.
• The Philips HS740/15 is a set of four replacement shaving blades for specific Head Pro models.
• The Remington SPF-300 is a set of two parts for the F5800 Titanium-X and F7800 Titanium.

A replacement foil on its own may seem like a cheaper option, but it won’t be suitable if the cutter block is worn out too.

3. Material, attachment and replacement interval

Check whether the part clips into place, screws on or needs to be fitted with a holder. Always switch off the device and unplug it or disconnect it from the charger before you start. The cutting surfaces are sharp, so avoid touching them as much as possible.

Replacement intervals vary by product. The product information gives a recommended interval of 12, 18 or 24 months for different parts. This is a guide, not a fixed guarantee. Heavy use, beard density, cleaning and damp storage can all affect wear.

According to the product information, Braun recommends replacing several of its original cassettes at around 18 months. Philips gives a 12-month interval for some parts, while two years is recommended for the SH91/50. Always check the manual for your device.

How to replace shaving blades safely

1. Switch off the shaver and disconnect it from the charger.
2. Remove the old cassette, foil or shaving blades according to the manual.
3. Check that the new part lines up correctly with the holder.
4. Clip or attach the replacement shaving head into place without forcing it.
5. Before use, check that all parts are secure.

Don’t use a damaged foil or bent blades. Keep loose shaving blades out of the reach of children.

Frequently asked questions about replacing shaving heads

How do I know which replacement shaving head will fit?

Note down the brand, series and model number of your device. Compare these with the part number on the product page. Also check the differences between a shaving head, cassette, foil and individual replacement shaving blades.

How often should I replace an electric shaving head?

It depends on the part and how often you use it. Product specifications give intervals of 12, 18 and 24 months. Replace it sooner if the foil is damaged, the device pulls at your hairs or you need several strokes to get the same result.

Do I need an original shaving head?

An original shaving head isn’t the only option in every case, but you should be able to verify that the part is compatible and attaches correctly. For parts such as the Braun 74S, Philips SH91/50 and Remington SPF-300, checking the specific model number can help you avoid buying the wrong one.
