Ivone was very knowledgable and helpful. She really had a great understanding of curly hair, as she was previously a hair stylist in Brazil. However, she didn't have much experience with ethnic hair, and the keratin deep conditioning treatment worked as well as if I put conditioner on my hair and let it sit. BUT she was a doll and very good at was she does, so I would recommend her to anyone that doesnt have ethnic hair. She did a great job on my roots (dye) and hair cut!
