I have been using the Suave brand for many years. There are times when I will buy the "compared to brand name" which in this case is Nexxus. But I do have 3 girls in the house and shampoo disappears in a blink of an eye! I seem to always go back to Suave.
The reality is that I cannot afford "the brand name". Why pay more for a shampoo? Hair in our house is washed every night and that is a lot of shampoo! I don't notice a big difference in using this one as to using the original brand and the fragrance is very similar. Yes, there is a difference but a very small one when you compare the price.
Suave humectant shampoo is for dry or damaged hair. Since most of our hair is blown dry and some even straighted with a hot iron, hair extra protection. This does an ok job. You do need a conditioner but that's another review!
