The major causes of frizz are scalp and hair dehydration. Curly hair is more prone to frizz because of the uneven distribution of oil across the scalp and hair. The cause of the uneven natural oils distribution is the large volume of curly hair that creates a barrier around the cuticles. Frizziness is exhibited by hair knots, tangles, and loss of coils and curls. Simply put, it is a mess and not something, you would want for your curly hair.
