Color damaged hair !!!Help !

Sheets • Ttc #1 3 years of marriage . Getting desperate ! But keeping the faith
I have recently bleached my hair and got bayalage . I had natural dark brown and now blonde highlights...but it only looked good for a week ! I use a organic shampoo but it's not doing any good . It's 3 weeks now and my hair feels and looks like straw!!!!! The color has faded ,it looks awful!!!!! I wish I could reverse it :( 
Any one can suggest a good shampoo for colored hair ? I have naturally wavy thin hair . I usually prefer sulfate free shampoos. Any other suggestion to help rescue my hair !!? Please help ! I'm in tears
