"My hair is frizzy/thick/wavy/curly and I wanted it to be easier and quicker to manage," Michelle says. She shares her experience: "The whole process took approximately five hours the first day and then two hours three days later. They applied [the treatment] in very small sections using a plastic comb and then sealed it with a flat iron ... I have thick below-the-shoulder hair and I would say this part took at least two to three hours." Despite the time-consuming adventure, "I would definitely do it again ... next time I will be better prepared with books and magazines," she says. Even after eight months, "the results are still evident" and the treatment seems to "not wear out, it just grows out," she says.
