Anything online is cheaper than personalized services. It's like shopping for ready-to-wear clothes, versus going to a tailor. The best candidates are those who already know what kind of hair and materials they need, and were professionally measured. They even know of a great hairdresser who can blend their haircut. Internet hair shopping is not for rookies. Any systems I sell online include my personal professional guidance. They are bought by my clients who cannot come to me, or who plan to come to me soon.
