Is the laser hair removal effect permanent?
The current laser or intense pulsed light therapy device has the function of permanent hair removal, so many people will misunderstand that the hair is not long after treatment, in fact, this permanent is not truly permanent.
The US Food and Drug Administration's understanding of permanent hair removal is that hair is no longer growing during a hair growth cycle after laser or intense pulsed light therapy.
In general, hair clearance after treatment with multiple lasers or intense light can reach 90%, of course, its efficacy is affected by many factors.
