From what I've experienced, as in with longer hair, using coconut OR argan oil is highly effective. You can also develop new grooming and hygiene habits, maybe over washing your hair is the problem: causing your hair to be unnaturally brittle, dry, and stripped of its natural oils that keep its sheen and protect its follicles. Try to figure out how often you actually need to wash your hair instead of every day. Just because society has standards doesn't mean they are healthy for you personally.
Try to use a comb instead of a brush to keep split ends at a minimal. Use leave in conditioners, try out different treatment options. I do know that while people with darker skin color usually have curly, hard-to-manage, coarse hair that is very fluffy, and that is due mostly with genetics and will be impossible to change.
How easy to treat your hair is also due to genetics, such as my hair is thick yet I'm white, and it's very easy to style (I can just run my fingers through it in a certain manner since it's shorter now, and it will stay in its place without gels or hairspray) So you will maybe have to ask around at a few places such as beauty parlors or barbers, hair product stores like Ulta or your local chain that sells alike products for tips. Also take to youtube, they give out some good bits of information!
