Like you, I have naturally thick curly hair and since I discovered Frizz Ease Dream Curls spray I very rarely straighten my hair. It depends on what your routine is but when I wash my hair, I towel dry it then brush it all over the front of my head with a wide tooth comb. I then spray the Dream Curls on, brush through again then scrunch up my hair and shake it out a bit. I then flip my head back and run my fingers through my hair to tidy it up a bit. My hair dries beautifully with minimum frizz and the curls are lovely and bouncy.
Give it ago and see what you think!
