Permanent Hair Removal : A Disputed Term - 2
What Is Long-term Hair Removal
Another undefined term is "long-term" hair removal. Again, it depends on what your definition of "long" is. The definition of "long-term" is being able to go 6 months after your final treatment without having to use another method of hair removal.
What Is Semi-permanent Hair Removal
A newer term used by some hair removal marketers is "semi-permanent hair removal." This is a marketing term used in the salon industry that some salons have started using to describe laser results. In the salon industry, it means "lasting a few weeks."
What Is Hair reduction & Hair Removal
Permanent hair removal has been established as the complete destruction of a hair follicle's ability to regenerate and grow hair.
Several lasers have demonstrated permanent hair reduction in clinical studies and are allowed to make this claim by FDA. The word "reduction" adds another term that is vaguely defined. FDA has accepted the definition of reduction as a stable reduction in the number of coarse dark hairs. Some lasers have demonstrated in clinical testing that they can reduce the size of hairs and lighten the color. In some patients, this reduction appears to be permanent.
