It’s difficult to assess a new hair removal method that claims to be eternal. Several people presume that after a specified amount of time, it’s doubtful that a hair will ever come back. That’s why quite a lot of people, myself as well, have suggested a specific definition of “permanent hair removal “. Generally of these definitions seem not good enough to me. One maker claims their method is permanent based on results after 8 weeks.
That’s comical. Waxing can last that long, and it’s been clinically proven to be temporary.

Permanent hair removal
For the purposes of hair removal, our explanation of “permanent” is being able to go a year after your last hair removal cure without having to use one more technique of hair removal. Bear in mind that a year might not be long enough to reveal factual permanence, but quite a few consumers would be content to have one treatment a year.
The sole method of clinically established  lasting for ever hair removal is electrolysis. Some lasers and flash lamps have been able to achieve permanent hair reduction, as discussed below.

Long-term hair removal
A different undefined term is “long-term” hair removal. Once more, it depends on what your definition of “long” is. Our definition of “long-term” is being able to go 7 months after your final treatment without having to use a new method of hair removal. Your definition may differ, but I don’t deem 8 weeks to be long-term. I subjectively decided on 7 months as a apt definition, because most hair growth cycles will have finished in 6 months.

Hair reduction vs. hair removal
Permanent hair removal has been accepted as the absolute destruction of a hair follicle’s capability to regenerate and grow hair.
Several lasers have verified permanent hair reduction in clinical studies and are allowed to make this claim by FDA.
The word “reduction” adds another term that is ambiguously defined. FDA has acknowledged the definition of reduction as a steady 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 everlasting.
