In my personal opinion because I have naturally curly hair and I went to beauty school, and I have tried all those fancy expensive products and I find a little bottle of Infusium at wal mart to work the best in my hair. Hands down, I buy the shampoo, the conditioner, and the leave in treatment, all three will cost you about $18.00 for all 3, they are about $6.00 a piece. Great stuff, I will never go back to anything else, I use a lot of heat treatment to my hair and my hair has never been healthier since I switched!!
