I have used DermOrganics for many many years. I used to work, years ago in the professional hair care industry for a manufacturer of professional hair care for the salon industry . I became a regional manager and a national trainer and worked at every major trade show in most of the US. I am very particular about my hair and what I use in it. The only thing I wish for in this line is a finishing spray. I always have to use something made by another line. Otherwise I use all the color treated line and swear by the hair mask. I will continue with Derm Organics as long as I have a hair on my head which I anticipate should be many years to come. God willing. Thanks for such a great product
