Really not a fan. Especially for the girl in the picture, I feel like her face is so pretty and fits a canon, only to have the hair completely detract away from those features. I think she would look so much better with her natural hair, and potentially up instead of down.
I can't imagine so many facial types that suit this kind of hairstyle.
I think it would look alright - however, you need to know that a lot of people will consider you (a white person) wearing dreads as cultural appropriation. I don't personally like it when a non-POC wears dreadlocks, but I'm not about to tell people what to do. It would not look bad, it would look good, but, over all wouldn't put off a good statement about you. I highly doubt you mean to offend, or upset anyone, but, over all it's never a good idea to do something that is seen as cultural appropriation. Whatever you chose, I hope you enjoy doing something new with your hair - just take note if you do chose to have dreads you're making a statement bigger than just changing your hair, and not a very positive one.
White people had dreads too. its isn't just a black thing. And yea they are cool im white and thinking about getting box braids with wave and having some blonde in their as well. You like them. get them.
