I highly recommend Evolve Detox Shampoo!! My hair has similar conditions. After I used this shampoo, my hair looks very shinny and healthy. The first time I used it, I am surprised to find almost 1/3 less hair loss. My roommate also tried once, less hair loss!!
It's a little bit expensive compared with other US organic shampoo. I just ordered bunch of it in feelunique.com. Today it has 10% off. Some people also recommend protein conditioner.
One more thing, you need to use conditioner after this shampoo. Same thing for all organic shampoo, I think.
I am using Desert Essence Tea Tree Shampoo right now. But I am kind of disappointed. Maybe less hair loss, but I cannot tell. Hair looks not healthy and shinny. Wanna try its apple ginger one next time.
