I tried some of the Curls line for the first time last night and my hair was super hard this morning.

I'm thinking maybe I put to much of the whipped cream in my hair. I used the washing cream/rinse, the coconut conditioner and the curl ecstasy with heat. Afterwards while my hair was still wet it felt so nice and soft. I then put the whipped cream in it and did a roller set and let it air dry. When I woke up this morning my hair was incredibly hard. What do you think I did wrong?
