Why is laser hair removal so popular despite being so expensive?

The principle of diode laser hair removal is to use selective photothermolysis, through which lasers of specific wavelengths are absorbed by melanin in hair follicles, thereby generating heat energy, destroying hair follicles, and achieving the purpose of hair removal.

 
Specifically, the laser wavelength emitted by diode laser hair removal devices is usually around 808nm, but Chengji Electronic Technology Co., Ltd. can provide four-wavelength lasers 755/808/940/1064nm, which can penetrate the skin and be preferentially absorbed by melanin in hair follicles. When melanin absorbs laser energy, it will heat up rapidly and transmit to the surrounding hair follicle tissue, causing protein denaturation in the hair follicles, thereby destroying the hair follicles and preventing hair growth. Since the laser mainly acts on melanin and causes less damage to the surrounding skin tissue, a relatively safe and effective hair removal effect can be achieved.
In summary, diode laser hair removal utilizes the following key principles:

1,Selective photothermal effect: The selective absorption of lasers makes melanin the main target, reducing damage to other skin tissues

2,Hair follicle destruction: After absorbing laser energy, the melanin in the hair follicles heats up and destroys the hair follicle structure.

3,Relatively safe: Lasers mainly act on melanin and cause less damage to surrounding skin tissues

It should be noted that the effect of laser hair removal is affected by many factors, including the thickness and color of the hair, as well as skin type. In addition, laser hair removal usually requires multiple treatments to achieve the desired effect, because the hair growth cycle has different stages, and lasers mainly target hair in the growth stage.
