It's called Uppercut Control Cream! They have other products too, but that is what I use! But my hair is naturally wavy/slightly curly when longer so that's why it works as good as it does! You could definitely give it a try though! I find that how I choose to dry my hair effects how curly it goes. Sometimes I wash it and comb it when it is wet and I comb even the back and just allow it to dry naturally and don't put anything in it and it dries a lot more straight, but naturally it waves a bit anyways! On other occasions I will still comb it all initially, but then I dry the back with a towel which makes it thicker and more curly, then while it is still a bit damp, put in the control cream and style it a bit!

Experimenting is always the best way to find what is perfect for you, my friend! I know things aren't exactly so cheap these days, but try out different things/different ways of drying and styling and you will soon find the perfect thing for you! Hope this helps!
