The one tip I have is for people with (long) curly hair that can go frizzy. Some products are ok for that but I find my hair usually gets greasy. I use L'Oreal Kerastase oleo relax. It's quite expensive but you don't need a lot of it and after using it my hair looks like I've been to the salon! I try to use biological products for my hair etc so have a bio shampoo and conditioner. Research has been done on the amount of toxic crap we put on our skin and therefore in our body by using regular shampoos. Scary. After having seen a special on tv about it I decided to change my shampoo and stuff and the L'oreal is the only exception to the rule as it makes my hair feel really nice
I hope that's helpful for you too.
