The question asked a lot is are cornrows bad for you hair and if so to what extent? The answer is no if you take care of them while they are in. Many women use the cornrowing of the hair as a protective style in order to wear wigs or protect their ends.
Once it’s braided or plaited up it requires less maintenance like combing or brushing which pulls and tugs on the roots of the hair. Cornrows give this small problem a break for a while. So I would say that this is a good way to wear your hair if you are looking to protect it a bit.
