The use of lasers for hair removal has been studied for a number of years. In this procedure, the laser device is consumed by melanin in the hair’s base, damaging the follicular epithelium.
Laser Hair Removal:
Laser techniques focus on the endogenous chromophore melanin, which is mainly found in the hairs base, with a small amount present in the upper third of the follicular epithelium. When an appropriate way to obtain energy (such as a laser) is directed at the skin, light is primarily consumed in the hairs base melanin. Heat is produced and diffuses to the surrounding follicular epithelium. An identical principle applies to laser device treatments of general lesions, where the heat produced after consumption by hemoglobin is transferred from the blood to the general endothelial cells.
The procedure of Laser Hair Removal:
Laser techniques are based on the principles of selective photothermolysis. A combination of the appropriate laser device wavelength, pulse duration, and fluency. Wavelengths between approximately 700 and 1000 nanometers (nm) are selectively consumed by melanin; the competing chromophores (oxyhemoglobin and water) absorb less energy at these wavelengths. Determine 2 shows the consumption of different chromophores in the skin. Therefore, any light that operates between 700 and 1000 nm is appropriate for targeting the melanin in the hair’s base.
There is a difference between long-lasting hairs decrease and finish thinning hairs. Complete thinning hairs imply that there are no regrowing hairs. This can be a brief or long-lasting phenomenon. The Light Sheer Diode Laser usually produces finish but short-term thinning hairs, followed by a partial but long-lasting hair decrease. This is an important distinction to make when setting patient expectations. With this laser device, 100% of the sufferers experienced short-term thinning hairs, while 89% of the sufferers had long-lasting hairs decrease at one-year follow-up. Of the 11% of sufferers who did not have long-term thinning hairs, most had brown hairs. Because brown hairs contain less melanin than darker.
