About one month before the treatment intensive solar radiation should be avoided. Therefore, 3 to 4 weeks before the treatment solarium and sunbathing should be avoided. This is justified by the technique of the alexandrite laser, since the bundled light impulses are blocked by deep tanned skin. Since the hair roots cannot be reached this way, the treatment would not only be ineffective but also dangerous, because the consequence would be burns.
Every hair removal method, which removes the hair root in the to be treated body area, should be avoided at least two weeks before the treatment stars. This applies to epilation, waxing or plucking but also the usage of depilatory cremes and bleaching. It is possible to shave directly before the treatment. If a permanent hair removal in the facial area should be performed, then it is necessary to remove any make up and to cleanse the facial skin thoroughly beforehand.
Since the alexandrite laser is equipped with an innovative cooling system, it is not necessary to numb the area for this painless treatment. If any slight redness still occurs during the treatment, it will heal up within one to two days completely.
The duration of the single sessions complies with the size of the body area, which is to be treated. A treatment around the upper lip is about 10 minutes. Whereas a treatment for the legs needs various sessions, which are each about one hour.
Due to the growth cycle of the hair various follow-up treatments are needed for a permanent hair removal with light therapy. The hair grows in three different cycles: After the growth phase, the transition phase follows and ultimately the resting phase takes place.
Since only hair can be treated which is in the growth phase, only about one third of hair can be treated during one session. The remaining hair is at that point in time in another of the both phases and cannot be reached. It takes about six to eight weeks, until the hair gets to the next section of the cycle, so that a different part of hair can be treated. For this reason there are always various sessions necessary to remove all hair permanently.
The treatment with an alexandrite laser is especially effective for people with fair skin and dark hair. Because with this distribution of the melanin, the bundled light waves can pass through the fair skin gently, then the dye inside the hair transports the light effectively to the hair roots. At this point the colour pigments are temporarily heated up highly, so that those denature. Hereby a chain reaction comes into effect, by activating the scavenger cells (macrophages), which are contained in the body. Those fight against the root of inflammation, hence the hair roots which are influenced by the light, and remove them permanently, so that the hair cannot regenerate itself anymore.
The endogenous reaction to the treatment with light therapy is variable. In general, the most suitable hair for a treatment with the alexandrite laser is dark and thick hair. Under these circumstances a treatment is possible for all body areas e.g. legs, bikini zone, neck or breast and facial area.
Since the hair removal with light depends on melanin, the dye inside the hair, grey or very light hair cannot be treated. Dark skinned people unfortunately cannot be treated as well, but there are different alternatives.
The effectiveness and durability of the hair removal with the alexandrite laser is proved by a medical long-term study. Visible results can be seen after the first treatment, so that the number and density of hair is reduced with every follow-up treatment.
When the final result is reached depends on the individual incidents of the patient. Generally speaking, there are about six to eight sessions necessary to achieve the perfect result in an extensive body area.
