How to grow hair longer without it turning into an Afro?

My hair is very dry and frizzy. I always keep my hair short, almost like military hair style. If it grows over an inches it turns into an Afro. I am not African-American so this is really strange. My hair use to be curly, but now it's just a a dry and frizzy afro when it grows. So I have to keep it short, but now I want to grow it at-least few inches.





So what can I do to grow my longer hair without turning into an Afro?How to grow hair longer without it turning into an Afro?
I've seen men who seem to have that issue. A pro would probably know better.





But my impression is that as your hair grows longer, the ends (which are the older parts of your hair) are getting more and more split - creating the extra volume.





It's possible that if you were to use a good moisturizer, split end preventer, or serum, you could control the volumizing effect.
