I personally prefer the dry shampoos so popular in decades past - all hail Minipoo! But washing hair is something most of us do and the quality of the water can affect your follicular scrub as much as the brand of hair detergent used. I am told that certain Hollywood personalities indulge their hairs with bottled waters. And who can argue, judging from how lovely most of them look when they walk down red carpets, perform in front of cameras and probably even when they go for a colonic. I hope they are not using the flavored waters or they might be providing bed & board for head lice. But I am told all stars must have a complete physical before starting a picture and I'm sure the doctors would catch any suspicious scalp activity.
