What do you mean by natural? You can try a biotin shampoo. The right shampoo can make a big difference, at least for a while. Also, if you use the same shampoo/conditioner for too long, your hair will get used to it and go flat. Find some shampoos you like and just go back and forth between them, but don't let it make you think you never had hair loss. I let a shampoo change fool me for a while. I probably lost some ground doing that.
