my hair did the EXACT same thing. one side is like 3c 4a 4b and a little 4c and the other side was like 3b 3c... but it changed after i gave up on heat for 5 months, they're not exactly the same but they are very similar now and i am happy, the side that was tighter does shrink up a little more but i''ve learned how to deal with it... being natural to me means to be able to work with what God gave you, i feel like thats where i wanna be..
