So it's almost exactly two weeks since my first session. I went to one of the high-power places that needs a medical license (at least in this country), but my somewhat light-colored hair and total lack of pain during the procedure made me really worried. The first week or so showed no progress, the hair seemed to be growing as normal. Then it got a bit thinner, or maybe I was imagining it?
But no, just today, it's been a whole day and almost no stubble or shadow! About 80% has just vanished (most of what remains is on my upper lip and beneath the jaw). I realize that the dormant follicles and so on are going to wake up soon, but I've still got several sessions to go.
So if you've just started and had the same worries as me, really: wait two weeks!
I am unreasonably excited about this. Sorry, past self who waited so long for his beard to come in: you don't need to worry about trying to look masc any more!
That has been my experience as well! Prepaid for 6 sessions so I set my expectations around that. Two weeks after my first, one morning ~90% of my hair wiped right off during my skincare routine. I was sooo excited! I seem to just have a few small active patches left which I'm hoping the second session helps with. Definitely putting money down for my legs and arms next time I go.
