I am going to have to completely and totally agree with the review above me, I have had many brazilians in my life and Salisa is very sweet and means well but I had a similar experience except I ended up having to go to the doctor because my lower area was in such a bad shape that I was in pain walking and even sleeping on my side hurt.
I think the following few things are indicative of her lack of expertise (although she has been in the business for a long time)
1) She went over the same area several times, granted if the hair is long then it is difficult to get all of it, but an experienced waxer knows that you do NOT rewax (my best waxer told me this herself and I have never been burnt) so she should have told me to trim at the salon OR explain that that rather than risk removing skin, there would still be hair left. I cannot tell you how painful it was.
2) I was burnt in the upper area although it didn't feel hot at the time and I think this was likely due to her going over the same area
3) I called her to explain what happened because I was in so much pain and the area was severely inflamed that I had to go to the doctor, she tried to be nice about it but said that I shouldn't have exercised or done anything after (which I didn't) or have sex (which I didn't) and even when I told her that my doctor said it was because of over zealousness...she just didn't want to say she did something wrong.
If she had at least accepted some responsibility. I would have been willing to try again if she had said "I am so sorry that happened, I may have been trying to remove the hair because it was too long but that may not have been the best idea so we will be super careful next time, it could also be because you have very sensitive skin." See? She could have semi put the blame on me on two counts, but simply accepting she did something wrong too or wasn't careful enough would have been better.
I am sorry to have to write this review because she is a really nice woman but it was very upsetting and so so so painful, I still have a little soreness in one area and it's been almost 2 weeks. Perhaps if you are very clear about the guidelines I mentioned above then it will be fine, she was not gentle enough but hopefully if she becomes aware of these problems she may fix them.
