Always replace both the foil and blades of your electric shaver or ladyshave together

Anyone who uses an electric shaver or a ladyshave daily knows how important it is for the device to shave smoothly and precisely. But what should you do when you notice that your shaver is no longer performing optimally, no longer cutting hairs properly, or even pulling them out? Many people believe that simply replacing the foil or the blades will suffice, but in reality, you should always replace both at the same time. In this article, we explain why replacing both the foil and blades is necessary for a good shave and to extend the life of your device.

How do the foil and blades wear down together?

The foil and blades of your electric shaver or ladyshave work closely together. The foil ensures that your skin does not come into direct contact with the blades, preventing cuts. At the same time, the blades cut the hairs neatly and efficiently. Over time, these two parts wear down together, meaning they become perfectly matched but also wear out together.
If you notice that your shaver isn’t cutting as well as it used to, it’s often because both the foil and the blades have lost their sharpness. This can lead to a less smooth shave and even skin irritation. At this point, it’s time to replace both components.

Why should you replace both parts?

A common mistake is to replace only one of the two parts, such as just the foil or just the blades. This might seem like a quick, easy, and cheaper solution, but in the long run, it can cause more problems and be more expensive. When you replace only the foil, the old blades will continue to wear down the new foil. Since the blades have been worn in to fit the old foil, they won’t match the new one properly, causing the new foil to wear out faster or even become damaged.
The same goes for replacing just the blades. The old foil is already adjusted to the old blades, and with new blades, friction occurs, which can quickly damage the foil. Before long, you’ll find yourself needing to replace both parts again.

Avoid damaging the motor of your shaver or ladyshave

Another important point to keep in mind is that if the foil and blades are not properly aligned, the blades can hit the foil. This happens when a worn blade or foil no longer works properly and the moving parts create too much friction. If this happens, the motor of your shaver can suffer significant damage.
The motor is the mechanism that drives the blades. When this mechanism is overloaded by a malfunctioning blade or foil, it can break down. This means that you not only have to replace the foil and blades but also potentially the motor or other internal parts of the shaver. This type of damage can be costly and, in some cases, may even require replacing the entire device.

By replacing both the blades and the foil in a timely manner, you prevent the blades from hitting the foil and protect the motor of your shaver. This saves you money in the long term and ensures that your device lasts longer and continues to perform optimally.

How to know when it’s time to replace your foil and blades?

There are several signs that can indicate it’s time to replace both the foil and the blades:

  • The shaver isn’t cutting as smoothly as it used to. This is often the first sign that something’s wrong.
  • You notice skin irritation. If your skin becomes red or sensitive after shaving, this could mean the blades and foil are no longer sharp enough.
  • The device is making more noise. Worn blades and foil can cause the device to work harder, producing more noise.
  • Some hairs aren’t being cut properly. If you find that stubble remains after shaving, it’s a clear sign that the blades and foil are worn out.
  • Hairs are being pulled rather than shaved. If you feel that the hairs are being pulled out rather than cut, it’s time to replace the blades and foil.
  • Visible damage to the foil. Visible damage to the foil is a sign that it is worn. A foil is typically a thin plate with many small holes. If the holes have become uneven in size or if two or more holes have merged into one larger hole, it’s important to replace the foil and blades immediately. Continuing to use the device in this condition puts you at risk of cuts or other injuries.

When the foil and blades are one unit

In some cases, the foil and blades are a complete unit, usually called a shaving head. This is common with certain models of shavers, where both parts cannot be replaced separately. In such cases, you’ll need to replace both parts together anyway, as they function as one unit. This simplifies maintenance because you can be sure that both the foil and blades are perfectly matched. This prevents the rapid wear that can occur when only one of the two components is replaced.

How to replace the foil and blades?

Fortunately, replacing the foil and blades is usually a simple process. Each shaver is different, but in most cases, you can easily find the replacement parts by looking up the model number of your device. This number is usually found on a label on the shaver itself or in the user manual.
