The treatments are usually spaced out 3 to 4 weeks apart for this reason. That schedule may be varied according to Dr. Ching’s decision on what will bring the best results for your hair removal. Hair can actually be in the active phase and yet be beneath the skin, unnoticed. Laser hair treatment can still remove these hairs even though they cannot be seen. The most important factor is that they are in the active phase, whether they have grown past the skin level or not. Although you can see some results after the initial treatment, the real effects will usually be seen starting with the 3rd session. That is because this is when the majority of hairs in the targeted area have been fully treated.
