Problematic hair....!!!!!?

I am using aussie shampoo, in the purple bottle. oh and when you do your conditioner leave it on for about 5 minutes, this REALLY helps, and when you straighten your hair, if you have a good straightener, you should do it sectionally. example, pull half of your hair up then divide the bottom into about 6 sections, straighten each individually, then pull down the middle layer, do the same, then the top, this helps tremendously, most people just try to straighten it all at once, that wont work. this way your getting it all and you dont need any type of product.
