KB, cornrows are a natural way of styling hair. Both females and males wear cornrows.

Also, women whose hair is permed {meaning straightened} may wear their hair in cornrows when their hair is permed.

It should be noted, that there's a distinction among Black people between straightened hair and hair that is naturally straight. There is also a distinction between curled hair and naturally curly hair. There's Black people who have straight hair, naturally curly hair, and curly-straight hair, and all other gradations in between.

It's common for Black people talk about the 'grade' of their hair and the grade of other Black people's hair. Though I've never heard it put this way, most Black people would give nappy hair a failing grade.

I remember when I first started to wear a natural {otherwise known as an afro or 'fro}, some Black women said that they didn't like the fact that women wearing 'fros were showing White people how our hair really looked before it was permed or straightened with a hot comb.

I think we've come some ways beyond that view. But I wouldn't be surprised if there are some sistas and brothers who still feel that way.
