AH! Well, my hair is porous, too, so perhaps I can help!
My favorite is SM's moisture retention shampoo. They also have a coconut and hibiscus line for curls, but for me I really love the moisture aspect for my porous hair. (I'm sure I'll end up trying the other at some point, tho! lol!!)
I use a couple of their styling products, too.
You can find them at Walgreens or Target, and can order them from either website or from drugstore.com.
Another I like that is a little stronger (has coco betaine) but still gentle is Organix Shea. (Organix has a lot of good ones, but watch for cones in the ingredients of that's a concern for you)
I don't know if you use any cones, but the SM won't remove them. The Organix would, however.
There are a couple by Renpure that people recommend, and by Giovanni, but I have not tried any of them.
All of those are drugstore available! (That's all I use, btw!)
