I am not sure the answer to cultural appropriation is to stop white people wearing black hairstyles though. I think cultural appropriation is sort of a legitimate thing but for me what is important is that society gets rid of its prejudice against black people eg that white people stop acting like Kim Kardashian's box braids are some new trend and acknowledge that black people made this style well known. And even more importantly, to stop telling black people their locks look scruffy while at the same time saying white pwople with locks look cool. Either say dreadlocks on ANYONE are "scruffy" or say dreadlocks on ANYONE are "cool."
The problem is that there are still negative attitudes towards black people deeply ingrained. Whether white people wear locks or braids r not is not going to change it, sadly.
I think black models and hairdressers and fshion designers need to be promoted more than they are being. Recently an afro hair products company came under fire, and rightly so, for only using white models to model their latest product. There is nothing wrong with white people using afro products at all.Many of us curly or wavy (anyone whose hair is type 2b upwards really) gals use them regardless of colour. BUT as the black people are the ones who need and use these products the most, they should be the ones advertising it? Or at least, a mix of black and white or Asian models. Black people should be allowed to have something where they are the focus, for once.
I reserve my right to wear or condition my hair the way I see fit but please, when we see a White or Asian celeb wearing braids or a weave or whatever, let us not act as though they have discovered some funky new style, as though their look hasn't been modelled on something black people have been wearing for centuries. Also, white hair, even if thick and curly can rarely cope with frequent braiding. The coarsest and curliest of caucasian hair is still a completely different texture to afro.
