On a related note, FWIW I know many people love the H2O products, but I find the hair products drying for color-treated hair (especially with the chlorine, salt water, and sun exposure during the cruise), so I recommend bringing your own shampoo/conditioner that is a concern for you at all. Everyone is different, of course, but I've seen it asked on here before and thought it worth mentioning if it relates to your packing plans as you're learning what is supplied on board.
