I had a Brazilian Blowdry and am really impressed with the results! My hair is naturally thick and quite curly but post-treatment is much more manageable and practically straight after a quick go with the hairdryer - joy!! My hair looked fine after the treatment, not at all greasy, so I left it for 5 days (instead of the suggested 3) which I think helped.
Therapist was nice and friendly. Only issue was the hot wax has been turned off so some of the bikini area had to be stripped waxed. However, on the whole I think it was good and would recommend Brazil hair
