Thanks for some of the great comments I have received! First off, I am not claiming to be a chemist (to an extent!). I have been in the hair field for 28 years, so for me it’s not only about designing hair but how it works. I research in my spare time and when I am applying color I am thinking about the process that is taking place in the hair shaft. Sometimes it’s hard for my brain to visualize the whole process. I would hope someday a child would not have to experience growing up without hair. When I learn all there is to hair it’s time for me to put the scissors down. A lot of people think hair is like growing flowers, water it fertilize it and beautiful flowers. The hair shaft does not get its keratin and moisture from so to speak from the ground up. It works more like when you spray the leaves of plants with nutrients which then are absorbed.
