Especially in cases of excessive hair growth, also called hypertrichosis or hirsutism, it makes sense to consult a dermatologist. If the diagnosis is correct, treatment can be considered. However, dermatologists also frequently undertake hair removal for aesthetic reasons.
Laser treatment for hair removal at the dermatologist
Laser treatment involves directing laser light of a specific wavelength onto the skin. The melanin, i.e. the pigment in the hair, adsorbs this and converts it into heat. This heat destroys the growth zone of the hair. The prerequisite for an effective treatment is therefore that the hair contains sufficient melanin. Therefore, the treatment is not suitable for white or light hair. The heat produced can cause a slight sensation of pain. However, newer laser devices have integrated cooling to counteract this. Since only about one third of the hair is ever affected by the laser treatment – because only one third of the hair is in the so-called waxing phase at any given time – the treatment must be repeated several times in order to achieve a satisfactory result.
IPL treatment at the dermatologist
Treatment with IPL devices works in principle like laser treatment. However, a different light source, the flash lamp, is used. But here, too, the light is absorbed by the melanin and the resulting heat leads to the destruction of the hair root. Same principle, same limitations: IPL treatment is also limited to darker hair. Particularly good results can also be achieved with light skin, as this is less heated by the light.
Success of hair removal at the dermatologist
The following applies to both methods: Several treatments must be carried out. In addition, the hair does not fall out suddenly during the treatment, but is gradually shed by the body.
