Well firstly, even though I havent finished reading it yet, that website is a load of bull**** pardon the expression but it is!! here's some quotes:
"It is also important that the beauty therapist removes the eyebrow hair in the direction of the growth. When hair is removed in the opposite direction greater stress will be placed on the skin, and ingrown hairs will commonly result"
"Salons must ensure that they maintain a hygienic premises, with all equipment properly sterilised, and never re-use waxing products"
Not to mention many other errors I've seen on there. For solicitors they're not so muh with the accuracy are they??!
I hate the ambulance chasing culture and these types of scavengers should be outlawed... BUT........
Read some of the case studies on their website. Some of the injuries they claim to have represented should damn well have been compensated. Spilling wax on someone is nigh on impossible if you have two braincells to rub together, how the hell do you spill your wax pot? But on top of that for your wax to be so hot it blisters the client? Outright negligence in my opinion and if that was me I'd want compensating too. Another case study (which made me cross my legs and say oww!!) The lady whose labia was ripped in 2 after a hollywood wax where the therapist didnt stretch the skin and it tore (also reads very much like she was using strip wax in the intimate area too). Again, this sort of thing is downright negligence and I'd want compensation for it.
The only worry for me (which I'm checking with my insurers on tomorrow) is this whole patch testing business. I dont patch test anyone for wax or nailsl, perhaps I should be doing?
Other than that I'm not too worried. If you are being damn well incompetent, you deserve to get sued. If someone tries to sue you for something and nothing, or something that wasnt your fault then I would say dont sweat too much over it, just because someone threatens to sue you doesnt mean they will succeed.
