hair mousse??

what’s the best hair mousse to use to keep my curls defined. i have some design essentials but there’s barely any left, and i wanna know what is the best one to get. do i keep getting design essentials orrr do i buy a different brand.

ALSO is gel okay for the whole head of hair for keeping curls defined?? or should i skip that part

For reference I have medium porosity, thick, long 4c hair. My mom never does my hair and I have school tomorrow so I need help asap.
