At the short length you have now, it's hard to know exactly what it will do when longer. Usually tighter curls like yours loosen up considerably with the weight of the hair, but not always ... and it's hard to know yet how long your hair needs to grow before the curl pattern changes significantly. You should just grow it out and see what you get. It will probably look great. It looks healthy and great already
Oh they both look really racially mixed and frankly, I think Fox's hair looks straighter than the OPs. But I agree with you about the texturizer suggestion: really bad idea for what he wants to achieve.
