Shampoo is shampoo.. just like The Donald says. Sure, I might get stuff from the salon every now and again i.e.( American Crew) but by and large, it's a waste of money.
Right now I'm using Suave two in one, simply because I love the aroma. They don't manufacture it anymore, but I managed to stock up on the stuff about 12 years ago when I learned they were taking it off the market. If I remember correctly, the price per bottle was around two bucks. It reminds me of what the original Pears shampoo was like before they started screwing around with the formula.
