Classical hair removal systems, whether laser, IPL, LEO-Tech and others, are highly developed, mostly well calibrated, work with single pulses and have a rather high efficiency. In permanent hair removal, they are aimed at the target melanin, the pigment of the hair that absorbs the energy, briefly heating the papilla to 70°C and thus destroying it. However, the side effects are a disadvantage here. The skin also contains melanin and thus absorbs energy. If the treatment parameters are not adjusted carefully enough to the patient’s skin and hair colour, burns and unsightly scarring can occur. In most cases a lot of treatment experience is necessary to define the correct parameters for each individual treatment.
The SHR technology for hair removal with laser only targets the melanin secondarily. Its primary target is the stem cells that produce new hair. SHR works with a low fluence but high optical energy and multiple pulses with a fast repetition rate of 10 Hz, i.e. 10 pulses per second. This new technology allows treatment in motion, i.e. you glide with the handpiece over the treatment area, it is heated, the sapphire contact cooling protects the epidermis. Light pressure when the handpiece is put on brings the necessary compression to keep any tissue fluids and blood that should not be heated away from the treatment area.

This and the new “In Motion” gliding technique represents a breakthrough in permanent hair removal with light, as the “pulse by pulse shot method”, which is generally known as with the previously known pulse light IPL and laser devices, with its associated undesirable side effects (chessboard, time) becomes unnecessary.

The precise positioning of the handpiece as with single pulse treatment is no longer necessary.

The treatment is much more pleasant than with conventional laser systems, as only about 25% of the energy is needed to remove the hair permanently. The lower the energy, the less the skin is stressed and the less pain is felt. A burn or scarring is no longer possible with SHR. With conventional laser systems, which sometimes use more than four times the energy, this risk is quite considerable.

The target dye is the protein of the stem cells. Therefore, even dark skin types and fine hairs with low pigmentation can be treated successfully!
In addition, treatment is also or especially useful during the telogen phase, since during this time the stem cells realign themselves for growth.

Already from nutrition we know that proteins lose their living and life-giving properties if they are heated above 43°C. The SHR technology enables the treatment area to be heated evenly to 45°C, whereby the surrounding tissue serves as an energy reservoir, i.e. the temperature of the hair papillae and their stem cells is also maintained by the surrounding tissue. After performing 6-8 passes, vertically and horizontally across the treatment area, perifolicular edema is usually formed, which indicates the success of the treatment. The stem cells were switched off.

The choice of the target dye now allows the conclusion that the hair growth phases have lost their importance for the cycle of subsequent treatments. After all, stem cells also exist in the telogen phase.
