Q: What is a flatliner made for and how should I use it?
A: The flattopper comb or flatliner is designed to give fast and accurate short haircuts and to create sharp looks.
The original flatliner, developed by Scottish hairdresser Brian Drumm, has a built in bubble level.
The liquid level inside the comb makes it possible to achieve precision haircuts and perfect flat tops at home and with little effort.
The tool is fairly easy to use. Place the flattopper vertically into the hair and glide the clippers
over the surface of the comb. Keep an eye on the liquid level to make sure that the flatliner is always level.
