I only sniffed WEN and it was so heavily perfumed, it made my eyes burn and then sneeze for nearly a half-hour. I'm not putting it on my head.
Plus, it's so expensive! I use VO5 from the dollar store, get the huge family bottle that lasts two weeks to wash, then slathered on my heavy conditioner. I'm paying $17 a month vs $30 for something that'd last a week at most.
