Hi all!! I am new to this, so stay with me please...

Ok... So I have a 5 year old daughter from what I can tell, she is a 3b underneath, 2c in the middle, 3c on the sides and 4a up top. Her 3b curls are gorgeous, but those sit underneath the rest of her hair, which is my problem. She is biracial, so we don't wash every day, and I have recently started cowashing, and a moisture treatment after, with a full wash once a week. Her hair is dry, and it's coarse in the 2c and 3c areas, and of course she has fly-aways. Ladies... I have tried everything (at least it feels that way), I have an entire shelf of products that have done nothing for her hair. I need a regimen that will help me get her beautiful curls all over, so she doesn't have to wear her hair up all the time.
I just purchased the Argan Oil line from Sally's. The shampoo, conditioner, hydrating mask, curl cream and styling cream, and oil treatment. So far, results have been less than the last product line I purchased, which was the Silk Elements Mixed Silk line and the SE MegaSilk Moisture Treatment. I was also using Cantu's Shea Leave-in. There is a list a mile long of things I tried before those, so we'll just leave it at that..
I have considered ordering the Mixed Chicks line, but with not so great results from the generic version, I'm not to eager to any more, maybe I'm wrong? I did just order the Curl Perfection Starter Kit from Carol's Daughter with the Hair Milk Shampoo, Conditioner, Original, Lite and Healthy Hair butter. I also threw in "Some of Marguerites Magic". The reviews I read before I ordered it were great, now that I ordered it, I'm seeing nothing but negative feedback... Any suggestions? I have to comb her hair every day, her hair is more like mine, I am hispanic, just lacks the moisture like her SD's. Also, when her hair dries, it poofs straight out like a lion mane, there is no weight to her hair at all, so any suggestions for that is welcomed!
So I'm looking for some help on a routine, do I use gel or hairspray to set it, how to keep it at night, how to keep it moisturized and how to get her curls poppin!!
Any help is appreciated!!!
