Replacing an electric shaver head: how to choose the right part

Replacing an electric shaver head seems straightforward until you discover that many parts only fit specific models. The wrong cassette may feel loose, shave less effectively or fail to connect properly at all. A cheaper compatible part is not necessarily better value if you have to replace it again soon afterwards.

This buying guide will help you choose an original replacement shaver head, replacement blades or a compatible shaving head for electric shavers from brands including Braun, Philips, Xiaomi and Remington.

Common pitfalls when choosing replacement shaver heads

1. Looking only at the brand

A Braun shaver head is not suitable for every Braun device. The Series 3, Series 5, Series 7 and Series 8 use different cassettes. Always check the exact model number on the shaver or in the manual.

Examples include:

  • Braun Series 3: 32B
  • Braun Series 5: 52S or 54B, depending on the generation
  • Braun Series 7: 74S
  • Braun Series 8: 83M
  • Philips 5000: SH50/50
  • Philips 9000: SH91/50

A product title that only says ‘suitable for Braun’ or ‘Philips shaver head’ does not provide enough certainty.

2. Confusing a marketing claim with a guarantee

Brands may state the number of cutting actions, comfort levels or an extended service life. According to Philips’ own information, for example, the SH91/50 has 72 self-sharpening NanoTech blades and delivers up to 150,000 cutting actions per minute. These are product specifications from the brand’s description, not a universal guarantee for every user.

So also look for verifiable details such as compatibility, number of parts, materials, attachment method and recommended replacement interval.

3. Replacing the foil without checking the whole system

With foil shavers, the cassette often consists of a foil and a cutter block. With rotary Philips models, you usually replace several shaving heads at the same time. Replacing just one part is not always enough.

Also check whether the device needs to be dry during replacement and whether the new head clicks firmly into place. Do not touch sharp cutting edges with your fingers.

Which specifications should you check?

Compatibility with the model and generation

Make a note of the model number before ordering. Pay attention to differences between generations within the same series. A Braun Series 5 shaver head marked 52S is not automatically interchangeable with every Series 5 model. The same applies to a Braun Series 7 shaver head or a Braun Series 8 shaver head.

The series designation is equally important for Philips. The Philips 5000 shaver head SH50/50 is designed for Philips 5000 Series shavers. According to the product information, the Philips 9000 shaver head SH91/50 is suitable for S9xxx and S9000 Prestige models from the specified ranges.

Type of shaving system

Choose the part based on the system:

  • Foil or foil-shaver model: usually a cassette with a foil and cutter block, such as Braun 32B, 74S or 83M.
  • Rotary shaver: often a set of three round shaving heads, such as Philips SH50/50 or SH91/50.
  • Hybrid trimmer: uses a separate replacement blade, such as a Philips OneBlade blade.
  • Trimmer or hair clipper: check whether you need a complete head, attachment comb or just a blade unit.

A trimmer head is therefore not the same as a shaving head for an electric shaver. If you mainly maintain different beard lengths, a complete trimmer may be more useful than a smooth-shaving cassette.

Replacement interval and maintenance

The correct interval depends on usage, hair thickness, cleaning and exposure to moisture. The product information supplied for various parts states the following:

  • Braun cassettes: according to the brand description, approximately every 18 months.
  • Philips SH50/50: according to the product description, approximately every 12 months.
  • Philips SH91/50: according to the product description, approximately every 2 years.
  • Philips OneBlade QP624/50: according to the product description, each blade can last up to 4 months.
  • Philips HS740/15: according to the product information, approximately every 6 months.

Treat these periods as a guide. Replace the head sooner if the foil is damaged, the device pulls at hairs or you have to apply noticeably more pressure. Clean and dry the head according to your device’s manual.

How to replace a shaver head safely

  1. Switch off the shaver and unplug it or disconnect the charger.
  2. Dry the device if instructed to do so in the manual.
  3. Open the lock or press the release button.
  4. Position the new head in the correct direction and check that it clicks firmly into place.
  5. Do not touch the cutting edges and only test the device once all parts are securely fitted.
  6. Only reset a replacement indicator according to the manufacturer’s instructions.

Only use a cleaning station with the correct cleaning cartridges. According to the product information, the Braun CCR 6 is designed for Braun SmartCare Centres and is supplied as a pack of six cartridges. A cleaning cartridge is not a replacement shaver head, but it helps maintain the device.

Frequently asked questions about replacing a shaver head

How do I know which shaver head fits my electric shaver?

Look for the model number on the housing, underneath the trimmer or on the packaging. Compare this number with the replacement head’s compatibility list. With Braun, check both the series and generation; with Philips, check the series and designation, such as SH50/50 or SH91/50.

How often should you replace a shaving head?

This varies depending on the part and how often it is used. Manufacturers often recommend intervals ranging from a few months to around two years. Replace the head sooner if it is damaged, pulls at hairs, becomes noisier or produces a noticeably less even result.

Is an original replacement shaver head always necessary?

Not always, but the compatibility and build quality must be right. An original part will generally have a clear model number and manufacturer’s specification. With a compatible part, pay extra attention to the attachment method, dimensions, materials and returns policy. This helps prevent a low purchase price from turning into an unusable part.
