Hair always looks better with any change in shampoo because the new one washes out the crud the old one wouldn't dissolve.
WTF?
"Crud the old one wouldn't dissolve" is a super poor way to phrase it, but it is essentially true. The "crud" is the buildup of the shampoo itself which gets nuked by the new brand.
I don't know if you remember the way old Neutragena Shampoo commercials claimed that using their shampoo every so often in between your regular shampoos would restore shine and blahbitty blah blah, but that is all that was about. Any change in shampoo will do this.
This also works with laundry detergent. It's why when switching to a new detergent, it almost always seems like the new stuff is so wonderful.
