I have had laser removal on my bikini, lower legs and underarms.
Yesterday was my 5th treatment, and now I will only have to go back every few years as new hairs grow in. :-D
I think I started the whole thing in Feb? It has been about $2500 total. I am very happy with the results, but it is very painful (to me). I have 16 tattoos and would much rather sit through one of those. I also had them put "topical" on me each time, which is at least $100 a treatment, but very slightly numbs the areas.
I have only had 2 treatments on my underarms (without topical), so far nothing growing back... but I had VERY little hair there to begin with, under 20 hairs. I also got a major discount because of my size (80 lbs) since there was not a lot of "area" esp. on my legs which are obv. very skinny. My legs and bikini have responded wonderfully. I have fairly dark brown hair and light skin, which is the best combo they said. I do know that they cannot use Laser removal on red hair, FYI.
I went to Premier Laser Center in Denton, which is very inexpensive compared to other centers. Good Luck!
