Laser hair removal works by the process of selective targeting of a specific area of the body and using a specific wavelength to absorb light into that area. It doesn’t work on a hair by hair basis, rather it focuses a wide beam of light that treats several hairs at once. The wavelength of light absorbed has to be sufficient enough to damage the targeted tissue area while making the neighboring part basically untouched. The principle guiding this process is known as selective photothermolysis.
Lasers are intense beams of monochromatic and coherent light. These light beams are generated by laser devices that have either minerals or gases. The four main types of lasers are solid state, semiconductor, gas and dye.
An electric current stimulates the gas or mineral properties which excites the atoms. The atoms then emit narrow, cohesive, parallel light beams which are all the same wavelength. The light beams are targeted only for a portion of a second on the dark hair pigment at the matrix of the dermal papilla, which is the small, cone shaped indentation at the base of the hair follicle that the hair bulb fits into. The light beam is absorbed and heats the pigment which vaporizes the dermal papilla. The more intense the light beam, the hotter it makes the pigment. This results in the dermal papilla being severely damaged or destroyed.
Most people think that laser hair removal works best on hair that is in its anagen phase. This means that the hair is actively growing and is attached to the dermal papilla. The theory guiding this belief is that if the dark pigment in the hair shaft expands entirely down to the dermal papilla, it will probably be destroyed and vaporized by the coherent light beam that’s targeted upon the area. This happens because the light beam will follow the dark pigment all the way down to the derma papilla.
Visible light has wavelengths that range from 390 to 770 nm, or nanometers. Lasers working in this vary permits for successful laser hair removal while not causing any harm to the dermal tissue. Lasers with a light source that operates between 700 to 1000 nm targets melanin in the hair shaft effectively. For instance, the wavelength of an alexandrite laser is 755 nm, that is red in the visible range of the electromagnetic spectrum, having its target melanin. The stronger, or greater, the wavelength, the deeper it penetrates target selectively absorbing the wavelength.
Laser hair removal makes use of several varying wavelengths of laser energy. These wavelengths vary from near infrared radiation to visible light. The 3 most generally used lasers for hair removal are Alexandrite, Pulsed diode array, and NeoDymium Yttrium Aluminum Garnets, Also referred to as Nd:YAGs. The wavelengths of these lasers are 755nm, 810nm, and 1064nm respectively.
Laser hair removal uses a complex system of science and physics that are precisely balanced to operate successfully and safely on the human body. As technology persists to progress in laser hair removal, this procedure continues to grow in popularity.
