Hi Pinkii,
I've worked with Thalgo. They do a lovely body range and they base their products on using the benefits of algae, so be ready for "smells of the sea" becoming part of the treatment! They do a wonderful slimming treatment where the serum smell of Mango (i think - cant quite remember) and chocolate. It also comes with a brown mask which leaves the client feeling lovely.
The training for Thalgo is done in London just near Canary Wharf, so for us essex babe's it's a trip down the A13 pretty much. Olivia, one of the trainers, is positively lovely, and the treatments include their signature movement of Modelage de la mer, which is a nice introduction of touch to the client to start of the treatment.
We had some aromatherapy associate stock too - the smell of their products got on my nerves after a while, but i understand that their body range is quite luxurious...
If you want any more info, let me know!
