Very dissappointed. I had brazilian done end of June with Cathee, through a groupon. I've had several brazilians done before, all which lasted 2 to 3 months. Cathee said her treatment would last 4 months, so I was excited. BUT it did not even last more than a week after I had the brazilian done with Cathee. I wonder if she even used any straightening Keratin treatment. So I was extremely dissappointed.
