ok so my hair is very thick and very curly when wet, but once it dries it expands and becomes very puffy making it look unhealthy but its not. what is the best hair stuff to keep my hair curly and unfrizzy/puffy?

If you want a straighter style, try to use shampoo for straight hair, like Garnier Fructis Sleek and Shine, or Redken or Frizz Ease. John Frieda has good products. If you want your hair to be curly, try Garnier Fructis Curl and Shine or another product for curly hair in the other brands that I named. I think if you use the products for straight hair, it will ease the puffiness/frizziness.
