Testimonials
The early 1990s, I made this decision to switch to Wella Hair exclusively for the Bumble and bumble salon. As we had been using a mixture of 4/5 hair color brands, this was an extremely difficult transition. At that time, we had nine colorists and we were one of the busiest salons in New York. The first week of transition was extremely difficult with everyone completely confused and the results were varied.
It was at this point that I first met David Velasco. He had just finished a long stint as the art director and head colorist for Wella US and he very much wanted to come work at Bumble. I hired him specifically to try and help us make sense of this new color methodology that we were going to be using. With David's help, things changed and improved almost immediately. Apart from his quiet leadership and charismatic way, he was simply never ruffled. Further, he has a very deep understanding of the basic concepts of hair color as well as the complex tasks that some clients choose to do. He managed very quickly to make sure that all nine colorists were confident in the new haircolor and made sure they continued to broaden the skills and knowledge that they were missing and strengthen their techniques. His overall personality and experience were huge boosts to a salon that had over 120 employees.
After five years, David decided to return to his own salon. However, he had made an indelible mark on the quality of work that our hair color department was able to produce. I would say that every salon in America should have his books. It is a must read, must know, must study series.

If you have David's books, you’ll see how easy it is to understand haircolor. Its been explained so basic and easy that everybody from experienced or beginners can understand it very well.

To anyone interested in professionally coloring hair, David's books are well worth the investment. They are very affordable if purchased one at a time but, if you get one, you will want them all. I have often read that his books are "the Bible of haircoloring", but quite honestly, they are much easier to understand!
Edi LePere
I have them all and they are fab......

Dear David,
When you told me that you were writing a book I knew that it would be good, but what you wrote is the encyclopedia of haircolor!

Dear David ~
I am a former education director for a major manufacturer and after almost 22 years, I'm still hungry for knowledge! And, after all these years, I'm still fascinated and frustrated by many of my fellow colorist's lack of knowledge and lack of interest in searching out or even making themselves available to information, tools and techniques. Just recently, I was fortunate enough to receive an email that contained your newsletter with all of it's categorized 'tips'. My reputation as a 'color geek' is long and well known, and I find myself the recipient of articles on the subject quite regularly. Not until today have I received something that made me stop in my tracks and realize that the ultimate comprehensive materials are readily available in your books.
Your ability to explain the realities of color/chemistry and the behavior of the hair's anatomy in relationship is outstanding. Your language is concise and to the point, leaving no doubt of what you are trying to convey. Each category has compelling information which simply relies on the 'core' of color theory to support any decision and/or formulation that is required for a successful and beautiful color result! Bravo!
I had given much thought over the years to writing such a book, but just didn't know how or where to begin; not so much for personal gain, but for the sake of the stylist AND client. Our young (and not so young) stylists rely too heavily on what they learned in beauty school - (and unfortunately some of that information has been deemed inaccurate or obsolete) - or they feel that they've complete their learning journey and are too proud to admit or confront that learning is ongoing and everlasting ... and exciting! THANK YOU for taking the time in writing such a much needed and well thought out 'encyclopedia' of hair color information. I smiled throughout the entire read and nodded my head in agreement, completely thrilled that there is a reference/learning tool out there that will once and for all cover all things imperative and important in approaching hair color with professionalism, confidence and integrity!
I am urging our salon to utilize your book as an educational implement to fine tune our colorist's approach to color, to create envious results through formulation and technique and to establish a code of integrity in dealing with challenging hair types! Your book is my bible and one that I can use to support the salons
goal of excellence in service and performance.
My appreciation and best wishes to you!
Karen Becker
Thank you very much you are so nice for share all your information
