Fashintern, thanks for the clarification, I definitely misunderstood you and maybe I still am? I have no knowledge of how frequently people find the need to change their hair products or how long most people test a new product before committing to a larger (than sample) sized container. I did not mean to imply this is a permanent choice, however I am happy enough with the results to try continuing my use of this product line to see how it goes over time…..
