I have tried a fair number of hair shine polishes. This product does more for my curly hair in any weather than any I have found. It keeps my hair shiny and curly even in terrible humid weather. It totally is worth the money you spend on it.
This is similar to Paul Mitchell's Super Skinny serum. To be honest, I really like this product (smell, feel, etc.). However, it's a little more costly than Paul Mitchell. However, it does look and feel good.
