Hello, Natu and welcome. 
If you want to try WEN, there's lots of ladies here who use WEN that can help. If you want to try a shampoo and conditioner, I use Nick Chavez Traditions Yucca Root shampoo and conditioner. The shampoo tube says "moisture" on it, so that might be good for your hair if it needs moisture. Although, Nick's Traditions Yucca Root conditioner isn't a leave-in conditioner. But Nick does make other leave-in conditioners.
Whatever you try, hope it works well for you.
