5 Factors will affect laser hair removal result - 3 & 4
3. Hair Cycle
Impacts laser hair removal procedure is hair growth, but it is not all hair are on the same growth cycle even if the hair is in the same area of the body. Therefore you will almost always need more than one procedure to completely treatment one area.
4. External Factors
External factors can also affect the outcome of laser hair removal procedure.
Tanning or sun exposure : All laser hair removal candidates should be at their lightest skin tone at the time of treatment. Having even the slightest tan can make it harder for the laser light to pass through your skin in order to heat the hair follicle.
Being a light skinned person with a light tan makes the treatment more difficult than being a darker skinned person who has no tan or sun exposure at all. Your practitioner may even give you a topical bleaching cream to apply in the days or weeks before your appointment and regular sunscreen use is recommended.
Herpes : The heat from the laser light can cause a herpes infection to become active if it is in the location of the area to be treated.
History of scarring : A history of abnormal scarring can lead to scarring directly from your procedure.
Scarring is usually not of high concern to those that do not have this kind of history, but if you do then you should discuss it with your practitioner before the procedure begins.
