I used to think clarifying shampoos were for people who used gels, hairsprays, etc. on a regular basis. I didn't so I didn't think I needed to clarify. Since buying Suave to clarify (only because Suave was dirt cheap), I have been reborn! I love that stuff!
There is nothing like it. Even if you were to wash your hair with regular shampoo like 3 times over, it is not the same as using a clarifying shampoo. The clarifying shampoo removes buildup and dirt but it does not dry out my hair. I used Garnier Length and Strength shampoo ONCE and it dried my hair out so badly. Not with clarifying shampoo.
The cheap one works for me so I would not recommend paying a lot for it.....unless someone has had a different experience.......
