My daughter-in-law is my hair dresser. She introduced me to Pureology a few years ago. Because I dye my hair quite often, I knew that I needed a shampoo that would be good for my straight, thin, dyed hair. When I use Pureology I know that I am getting the best possible results for my hair. I like to wash my hair every day and I am not worried about shampoo build up with Pureology. It leaves my hair feeling full, nourished and soft. My husband also uses Pureology's shampoo, conditioner combination for men. It has a minty scent and he loves it. I love Pureology and I would highly recommend it to anyone with any type of hair. It is a little more expensive than grocery store shampoo, but the quality is 100% better and it is worth the extra cost. Effectiveness Pureology super smooth shampoo is great for my hair. My hairdresser recommended it because I have straight, thin, dyed hair. Scent I love Pureology's scents. I have tried several of their products and have loved every scent. I really like the mint shampoo that I just purchased.
