The problem when you call is that you speak to some idiots in a call centre. I would recommend actually going to the clinic and talking face-to-face. Or book a test patch and ask your questions then. To date I have had:
3 treatments for legs/butt with about 50% reduction, I had the 4th treatment today. I had a 20 week gap between treatments 2 & 3 and the reduction was very impressive even after 2 treatments.
4 full back - I had some coarse patches which are now completely gone, but I have induced hair growth evenly all over now, but this is reacting well also and is almost gone also.
4 arms - again very impressive results, similar to legs, but some induced in upper arm, but again this is reacting to further treatment and I will switch to electrolysis to finish off (I count maybe 200 hairs which need finishing off on the upper arm).
