I do agree with this but I also agree with what wifey said. As a non qualified hairdresser who has fitted extensions for 10 years is probably better at this than a qualified hairdresser who just done it once every other week for a month or so. There is so much more to this argument though, because there are those who go for a one day extension course and think they know everything, and there are those that take that course merely as a stepping stone and then go out and read books and learn more and practice and have a mentor that teaches them cutting techniques and even though they are never qualified as a hairdresser, their experience with hair and textures has left them highly competent to fit extensions. It is not so black and white and we can't think everyone is alike and just because they might not have gone down the traditional or preferred route does not always make them less competent. In the wrong hands a degree is sometimes just a piece of paper. It is more what you do with the knowledge you have and also that you continue to seek more knowledge, and that is true in all skills. That being said the ideal would be a qualified hair dresser that specialises in extensions and has experience in both.
