How do I get my hair curly again after using "regular" shampoo?

I started using DevaCurl last December and it has really been working for me. However, on a recent trip, I used a Suave shampoo and now my hair is dry, frizzy, and seemingly devoid of all of the nice curls I had before.I've been washing my hair with DevaCurl and using additional products for almost a week after and it still won't go back to normal. Help!(I've attached 2 photos: one of me with my hair as I like it and one after the horrible shampoo incident. You can see a little curl but not much in the 2nd photo. Also, my face is scribbled out because ew.)

Did the shampoo have silicones in it, or sulfates, or both? Also, how often do you deep condition?
Anytime I use Shampoo (Which is usually silicone and/or sulfate free, and I shampoo probably 2-3 times a month) I always follow up with a treatment (deep conditioning, masque etc). Otherwise I'm usually co-washing my hair every 4 days or so, and I still condition my hair once a week because I have dry, bleached hair.
