Worst customer service ever. Having spent over £3k like the other user, received absolutely…read moreappalling service and was treated like a thief after they ripped me off by one treatment due to the fact they have zero tracking system in their clinic. Staff will barge into rooms multiple times during treatments when you are in your underwear (or naked) and have no awareness or respect. The girl who sits at reception acts like she is the CEO when she is nothing more then a receptionist who is unable to do her job and has no awareness of how to handle customers. There are far better clinics, try the MBA clinic, much more professional service! Zero stars

If your looking to waste not only your time but money as well then go ahead and go to 'COLAZ'. I…read morehave been having laser treatments here for over a year and it so far the worst decision I ever made. I saved up for months to get 12 sessions on my face, arms and legs as after reading the reviews on here I thought it would work, but I was wrong! My hair now, after 12 sessions is growing much more than I even started off with, thanks to Colaz! If only I had known before that this was going to make it worse, I would of saved over £2000 which I spent on this useless treatment. Obviously I was told that I might have PCOS (they will use any excuse to get the blame off themselves). I was told numerous times to get a blood test done to check hormonal levels. After having blood tests done twice, the results showed up as normal and there were no signs of in balances. However, yet again the staff at Colaz still insisted that I should go for further scans done as the blood test is not 'enough'. So I went ahead and got the scans done too and YET AGAIN there were no signs of pcos or any kind in balances. The results were normal! SO this obviously means there was no problem with my hormones etc and in fact a problem with COLAZ's machines or the way they done my treatments. Obviously they cant admit their own mistakes and were offering a free session instead and then trying to convince me to buy more sessions because '12 wasn't enough'. ITS FUNNY HOW WHEN I STARTED THEY SAID 12 WILL BE MORE THAN ENOUGH AND YOU WILL SEE A HUGE DIFFERENCE. THE ONLY THING IM SEEING IS MORE HAIR THAN I STARTED OFF WITH! NO REDUCTION what so ever! HUGELY DISAPPOINTED!!! I have already warned all my family and friends to stay away from COLAZ. DON'T LET THEM RIP U OFF TOO!

Went to the Hampstead branch to have cavi-lipo by Kumar. The guy is super friendly and nice to talk…read moreto, guided me through the process and answered all my questions. I can't say anything bad about the guy, he seemed to be quite experienced in this and he did make a good discount at one point. The main reason why I am giving just two stars is a simple one: the treatment didn't work. I hardly noticed any type of difference in terms of fat loss. Even though the process did seem scientifically accurate, results are the ones that matter.

WOW!! I never knew I had eyebrows until now.. I am so amazed at the fantastic results I got from…read moreKully.. she is a sweetheart and a skilled expert all rolled into one! Tried so many different brow bars in the past (at all ends of the price scale) but never did I feel, or get compliments like this.. ;-) I wont let anyone else touch my precious brows again...ever!! Kully really does live up to her reputation.. I feel like a new woman after my threading and brow & lash tint.. Well worth the trip to Mayfair.. 5*

I've never had eyebrow threading done before. I met Kully by chance at work. She was really nice…read moreand approachable. I was impressed by her knowledge and expertise when she told me what her profession was. I've had problems in the past when getting my brows waxed. She knew exactly what she was talking about. I felt that she would be the best person to go to. I made the appointment the very next day to get my eyebrows threaded. When I went into the salon she made me feel wellcome and relaxed. She explained the threading procedure again and put me at ease. I was so impressed with the results I told everyone about her. My boss went down the next week and made an appointment. She also gave me tips on plucking my brows. I would never dream of going to anyone else now. Its safe to say that I will be a lifelong fan, and convert to the Upper Echelon school of brow threading. Thanks for everything. Ann.
