The product itself works great and smells absolutely lovely. Seriously the best scent I've ever experienced in a dry shampoo so far. The hair feels fresh and the product really does its job.
What really brings the rating down significantly is the bottle itself. Every time I've bought it, the spray function has stopped working long before the product is finished. Now I'm stuck again with an almost half-full bottle that can't be used at all, which is incredibly frustrating considering the price and how good the contents actually are.
