I’ve been a Purology loyalist for years, but at $50/bottle I was on a quest to find a cheaper shampoo. I switched to Aveeno, at around $6.99 per bottle on Drugstore.com. My hair is dry, frizzy and often looks dull. The Nourish & Shine provides a lot of moisture and at the same time your hair feels clean – no residue. As much as I loved Pureology the “no sulfites” could make my hair actually start looking dull if I did not switch it out with other stuff once a week. Plus, I love the fresh scent. A really good alternative to expensive shampoo.
