What is the name of the high-frequency current commonly used in the barbershop?

The high-frequency current commonly used in barbershops is referred to as Tesla current. This type of current is characterized by its ability to produce a rapid oscillation and is often employed in various beauty and barbering treatments. Tesla current is known for its therapeutic properties, such as improving blood circulation, promoting hair growth, and enhancing the overall health of the scalp and skin.

This current works by utilizing a high-frequency electrical current, which can also produce a mild sensation on the skin. It is particularly favored for its effectiveness in stimulating hair follicles, making it beneficial for clients experiencing hair loss or seeking improved hair health.

Other types of currents, such as galvanic current, involve a continuous flow of electricity and are primarily used for iontophoresis in skin treatments, while spark current and ripple current do not have the specific applications and benefits associated with Tesla current in the context of barbering. This reinforces why Tesla current is the correct choice in this setting.
