Therapie Clinic UK

I’ve now had 12 sessions for full leg with Therapie Clinic, and I’m just no where near being completely hairless. It’s definitely finer, and patchy but really not the results I wanted after 10 sessions let alone 12. I have quite dark hair and pale-medium skin. There was no patch test when I first started with them. They said they gradually increase the strength each session (doing a patch test of the higher strength at the end of each session in prep for the next one). But because you shave your legs before each session, they don’t see your results and you’re asked to put a percentage on your reduction when I have zero frame of reference. I was semi-pressured into booking a package of 3 after my package of 10 was used up, so I have my 13th booked in a couple of weeks. But then I have decided I want to try elsewhere. I have found an independent clinic that uses a laser that is a different brand from therapie but uses the same wavelengths (755nm Alexandrite and 1064nm YAG), do you think just a new (better) clinic would make a difference or do I need new/stronger wavelengths? When I have said I’m not experiencing the reduction I hoped, a laser tech at therapie said I’m on the strongest setting.

TLDR: Not getting the reduction I want at therapie, would the same wavelengths, different brand laser at a better clinic give the same results? What lasers/wavelengths have you found to be the best?
