Yes it is perfectly normal for your curls to be a bit hard and crunchy when using the Cantu Define and Shine Custard. I like to use an oil to help smooth out the crunch and to help soften the curls. You want to use your favourite hair oil (Coconut Oil, Olive Oil, Castor Oil or Jojoba Oil etc)
You do not need to use a lot of this and use the pam of your hands to smooth out sections of your curly hair to remove the crunch. I have a video here - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vjfDUP3x2Dg.html go to timestamp 11:26-12:00 to see a demonstration on how I remove the crunch from a curly hair product in my hair
