I'm obsessed with Shea Moisture! It's great on my hair and works well on DD too. (I'm white with type 2C hair). I get so many compliments after I switched to this. It comes in a big tub and is in the ethnic section of Walmart/Target.
Also, I often use a spray bottle of salt water on DD's hair after I brush it (it does need brushed in the morning if she showers at night). That helps reset the frizz.
