I'm so happy I found this site after deciding to start doing my own hair. I used Goldwell for 20 years in LA at my salon, and have recently moved and can't find anyone to use my custom color. Wish me luck- so happy they have instructional videos listed. I got the instructions from my old stylist as well. Cosmetic World was so helpful throughout the ordering process and shipped my products as soon as they were available! I'm happy to order again in the future.
