Will Change of Machine Effect the Treatment?

Only hairs that are in the active growth phase (ANAGEN) respond most effectively to laser treatment. Since up to half of the hair at any given time can be in the resting phase (TELOGEN), almost half of the hair would not respond.

That is why serial and multiple treatments are necessary. Also, hair growth cycles are different for different patients. This is usually governed by genetics.


1064 nm wavelength based lasers are the best for darker skinned patients while the others (755nm and 800nm based lasers work best for lighter skinned Caucasians). Consult a dermatologist laser specialist to determine the best laser for you

If your hair is light, there is no laser that will work for you.  If your hair is fairly dark and your skin is light, I recommend an Alexandrite laser.  Candela makes a great one.  This is what we use in my office.  Unfortunately laser hair removal does not work perfectly for every patient, and it is always difficult to predict exactly how many treatments a patient will need to have the desired outcome.

demi m,  If your hair is being resistant to laser treatment, you may want to consider having a hormonal workup done to check things like testosterone and DHEA-S.  There could be some underlying hormonal abnormality which is driving the hair growth.
