I'm new to all this, but I'm fairly sure my hair is naturally a 3a or b. But since having kids, lots of stress and an arid environment for years, my hair has lost it's curl. It's now looking like a 2a. I'm trying to get my hair back to its natural curl, but I need some help figuring out how to.

I like to make my own products, if at all possible, but I have no clue where to start there, either.
