Before I switched to Nexxus Aloe Rid Shampoo (clarifying), I used to use Pantene's Clarifying shampoo "Purity."
However, after joining this board and finding out how drying Ammonium Laurel Sulfate (sp?) was, I switched to the Nexxus.
But, the Pantene didn't SEEM to dry out my hair...I only used it occasionally. It was good for removing buildup and helping my curls spring back (at the time I had natural hair). And it was cheap!
