I always bring my own shampoo and cond when on vacation. It is a very good product which I always use at home with no problem. When I am at WDW I seem to have problems even with what I use. We feel so dried out and my hair seems dry also. We bring Dove for my son because he is sensitive to everything. I always just figured it was the water because I never used the samples. I did always bring them home though. Can't resist leaving them in the room when I figured I paid for them.
