I have bought a 6-session laser hair removal package for my bikini area. I have had my third session and the results are pretty good already as my hair is dark but my skin is fair.
On average, I have spaced out the sessions every 8 to 9 weeks. I am getting a lot of pressure from the place to book my next session 6 to 8 weeks max. after the previous one. However, because the results are pretty good, I find that the hair has not really grown back much after 8 weeks.
I would prefer to go every 10 weeks or so to ensure that all the hair that is to come out has actually come out.
I have been told by the nurse that going every 6 weeks or so ensures that hair at various stages of growth is zapped. mmmm... not quite sure how that would work, as I would have thought after 10 weeks, all of it (or 90% of it) would be out and could be zapped.
I suspect that they are telling me to go every 6 weeks for their own benefit rather than mine: i.e. so that my package is completed in the minimum amount of time.
In a way, I would be quite happy to do 5 sessions and then wait quite a few months to see if there is any regrowth and use my final session at my own convenience.
So, am I unduly cynical and is there truly a scientific basis to their claim that I should go every 6 to 8 weeks?
