Katie,
I am a Brit living in Florida with a Medical Spa - this is a facility where we have doctors and nurses offering Botox, weightloss etc. and Laser Hair Removal etc. (www.coastlasercenter.com)
We use a Diode Laser from Lumenis and it is great, I have looked at IPL and it is OK. Some of the opinions here from people are a little one sided. IPL is not as efficient as Diode, however it does work but it will take longer and more treatments but is a LOT cheaper. The real benefit is you can do other services such as skin rejuvenation with an IPL.
Hair grows in a 6 week cycle and as long as you are getting the shedding of the follicle, this will not come back for a long time.
ALL laser hair removal is NOT permanent! The body can always grow a new follicle, maybe in years ahead, and new hair will grow. What happens with IPL or Diode is that you kill your existing follicle. Both methods are better than Waxing!
I think the DepiCool model is a good one for the UK, the requirements in the US vary from State to State. In Florida you need a Nurse Practitioner or Doctor to run a laser for hair removal, in Texas any idiot can use one - and because they are more powerful you can burn holes in people and scar them!
I believe for 49 per visit that the DepiCool model is great value at “permanent hair reduction” and 8-10 treatments on a 6-8 week visit cycle with give you very good results.
I hope this help?
