help!!! i took Whiskey to the groomer's last week for the first time. I am excluding the other time i took her and the lady shaved her down except for her head- can we say bobble-head please

. anyway when i picked her up she looked like a completely different dog-her hair was all nice and flat (she's a fluffy thing!) and divided down her back. now i wash her once a week and brush her nightly with her c.c. brush but i can't get her hair to "do" like the groomer did. i would love some tips and advice. thanks
