There's a million shampoos out there, which one(s) do you use? I like the higher end brands, like Alterna Caviar & Umberto Beverly Hills, but I'll get a drugstore brand here & there, like Pantene & Neutrogena. I don't stick w/ 1 brand only. In my bathroom, I have about 10 different 1/2 used bottles that I alternate. I'm not buying any more for a long time!
