HairMaster: How to replace heating tubes
The heating tubes in your HairMaster are the parts that wear during use and can eventually burn out. Fortunately, replacing them is easy. Safety first: Turn off your HairMaster, unplug it, and let the head cool down completely. The heating tube is made of glass, so handle it carefully.

What you need
How to do it
Check the serial number
You’ll find the serial number under the head of your HairMaster. The serial number must be above 3,000,000 for you to replace the tube.
Preparation
- Switch off your HairMaster
- Let it cool down
Remove the grille
Push the metal grille toward the machine itself and pull/tilt it out. The grille is secured in two holes at the outer end of your HairMaster’s arm. Take a look before you start pushing/pulling.
Remove the old heating tube
Press the heating tube slightly toward one end so that the opposite end comes loose from the socket, then carefully tilt it out.
Is it stuck? Do not use force. Give the tube a gentle twist (turn it just a little) while pressing it slightly inward. Once it is loose, you can tilt it out without resistance—you’ll know—but it can be a little tricky with older machines.
Install the new heating tube
Do the same in reverse: Insert one end into the socket, press it in gently, and tilt the other end into place. The same applies here as before: Do not use force. Give the tube a gentle twist (turn it just a little) while pressing it slightly down into the socket.
Reattach the grille
In the opposite way to how you loosened the grille, guide it back toward the arm and press it against the machine itself to insert the grille into the two holes.
Switch on and test
Connect your HairMaster to power, switch it on, and check that the tube heats steadily and evenly.

Hairdressing chairs, styling chairs and salon stools: what’s the difference?
If you’ve ever searched for “hairdressing chairs” and ended up looking at a chair for the client instead of yourself, you’re not alone. It’s one of the most common points of confusion in the industry, and we’re clearing it up once and for all. In short: there are two types of chairs in a salon. There’s the chair you sit on. And there’s the chair your client sits on. It sounds simple. But in practice, the terms are often used interchangeably, making it difficult to find the right one when you shop online.
