Thanks for the answers.
Lagirl: I had never used any hair removal methods before on the area and never had any problems with ingrown hairs before. And during the treatments I did not have any problem with this, that is during the tree months of regrowth between each treatment. It only began after the last treatment and has continued now when I have stopped doing the treatments, so it does seem to be because the hairs have gotten too thin. And then I guess there is a risk that this will happen to an even bigger extent if I would decide to do laser to thin out more areas, since there will be more hairs that will be too thin then?
Dee: I will look into ways of exfoliating.
Thanks.
