Laser hair removal with a diode laser with four wavelengths is an advanced method for permanently removing unwanted hair. This technology uses the advantages of multiple wavelengths to effectively and safely destroy hair follicles.
The four wavelengths used in diode lasers for hair removal are 755 nm, 808 nm, 940 nm and 1064 nm. Each wavelength has different interactions with the melanin pigment in the hair and skin, allowing all skin and hair types to be treated. (except for gray/white hair)
- The 755nm wavelength primarily targets melanin in the superficial part of the hair follicle and is effective for removing fine, light-colored hair.
- The 808nm wavelength penetrates deeper into the skin and targets the melanin in the middle part of the hair follicle, making it suitable for treating a wide range of hair types and skin tones.
- The 940nm wavelength has a greater penetration depth and can effectively target the deeper hair follicles, making it suitable for treating thick, deep-rooted hair. This wavelength also works on the nutrient follicle, which ensures a faster and more lasting result.
- The 1064nm wavelength is specifically designed to work on dark and pigmented skin types, where melanin in the skin is minimally absorbed and the focus is primarily on the hair follicle.
The use of diode lasers with four wavelengths makes it possible to treat a wide range of hair colors and skin types, including lighter and darker skin tones. By combining different wavelengths, the treatment can be more efficient and effective than with lasers with only one or three wavelengths.
In laser hair removal, the laser pulses are focused on the areas to be treated. The melanin in the hair follicles absorbs the laser light, which is then converted into heat. This heat damages the hair follicle, slowing and eventually stopping hair growth.
The number of treatments required may vary depending on factors such as hair color, skin color, hair thickness, and the area being treated. Multiple sessions are required to treat hair follicles in different growth phases.
