I'm from Eastern Europe, paid around 15-20 euros per session, did 3 and is needed around 8-10 sessions, each 6-8 weeks. I went to an electrolisys specialist in my area and asked her to remove some of the forehead hair, that I previously shaved in a (failed) attempt to remove it with IPL light at home. It was mostly the middle of the forehead, around 1.5 cm, my hair grows in a V shape and I wanted more of a round shape, just be aware that, initially, it may look a bit weird without baby hairs that usually grows in the area, and also, hairs will regrow on the forehead randomly, depending if the root was distroyed or not (and is not possible to distroy all of them in the same appointment, each thread has different stage at a given time). This is why more sessions are needed.
As an unrelated side note, I was looking for a Kim Kardashian/ J Lopez type of hairline, I also used mynoxidil previously on the sides of the forehead to grow hair, and I'm pleased with the results, now my forehead is almost the way I wanted, instead of that V thing I had (it was like Leonardo di Caprio hairline)
