Painless and Permanent Hair Removal

Hair removal is a vague term that was recently defined with precision. Temporary hair removal as a delay of hair growth, the set usually 1-3 months after the induction of telogen. permanent hair removal as a significant decline in the number of terminal hairs after a given treatment, which is stable over a longer period than the entire growth cycle of hair follicles is applied to the body part.

The demand for quick hair removal non-invasively, the introduction of various light sources for hair removal performed. Hair removal source often focuses on ruby, alexandrite, diode and Nd: YAG and intense pulsed light sources. These devices are designed for a purpose, whether endogenous chromophores (melanin) or exogenous chromophore (carbon suspension, and a dye photosensitizer exogenous). Laser hair removal is one of the latest hair removal has been introduced. Today a large number of specific laser systems are commercially available, so that the customer can choose a little concerned about their Internet, treatment protocols and effects. Laser hair removal is one of the light sources of hair removal. Hair follicles are destroyed by light in a number of means, such as thermal mechanism, photomechanical or photochemical production of toxic mediators like singlet oxygen or free radicals.

thermal method of hair removal has recently been introduced to induce selective damage to hair follicles. Based on the principles of selective photothermolysis, this principle requires that selective thermal damage of a pigmented target structure occurs when light of a specific wavelength enough through the goal at a time or less absorbed thermal relaxation time of the target.

Melanin is the natural chromophore for the management of the hair follicles visible to near infrared laser or light sources in the wavelength region are red or near infrared spectrum of optics, combined with selective absorption by melanin deep penetration into the dermis. Therefore, the deep and selective heating of the hair shaft, and heavily pigmented matrix Haarfollikelepithel is possible in the region 600nm to 1100nm. However, melanin in the epidermis presents a competing site for absorption. Selective cooling of the epidermis has been shown to minimize epidermal injury.

photomechanical destruction of the hair with very short nanosecond pulses treated. Performed using the Q-switched 1064-nm Nd: YAG laser with or without carbon suspension. Short pulses are used to the hair follicles in rapid heating of the chromophore (melanin) target. This leads to acoustic shock waves, the coordination of photo photomechanical melanocytes but not complete follicular disruption interfere. Therefore, the Q-switched Nd: YAG are not likely to produce long term hair removal.

It must be made to distinguish between permanent hair loss and complete. Immediately after laser treatment, the hair shaft shows fragmentation of the holding points of the follicular epithelium and thermal damage to the surrounding follicular epithelium. The extent of thermal damage depends on the pulse width, but retains the spatial confinement of the follicle. Histological changes are almost guaranteed by the person in laser hair removal. However, this form of hair removal under the supervision of a qualified dermatologist will be carried out, since it is connected to a high degree of specialization.
