My little brother has been a stoner since he was 11. I've seen his hair in dreadlocks a couple of times, he was well known for it on the cricket scene. I just get short back and sides, no guard. Short on top. I'll probably be going full skin head by the end of the year cos I'm receeding quite quickly now.
No, they don't. There are examples of dreadlocks in the history of a wide variety of cultures. Ancient Greece, Egypt, India, the ****ing vikings, the Germans, the Celts... it's just very widespread.
So did India. Like a lot of things, dreadlocks predate our knowledge of history. They're incredibly widespread, because of their very nature. Different cultures stumble upon them independently. It would be like asking who first worked out how to create fire or make a wheel. Cultural appropriation is pretty stupid anyway, but when it comes to something like this, then it's even more stupid. Telling people that they can't style their hair how they want to because of their skin colour is utterly moronic. Unless it's specifically done to insult or provoke, then it's not harmful or offensive.
Had curtains when I was a young kid. I got a Beckham/ Chuck Liddell mohawk once when I was in primary and got sent home as the **** of a headmaster deemed it inappropriate. I thought I looked slick and gangsta. For roughly just under a year, I had that style which was like a mohawk though you had a full head of hair but all the way through the middle it was longer and gelled/ waxed upwards, not sure what the style was called, "knobhead style" would do it justice, embarrassed I used to have it but it was the 'in-thing' back in secondary. Outside of those little fad moments, I've sported a simple French crop for most of my life, although now at 28, my hair is beginning to thin so I've just been using the clippers and doing a one all over in recent months.
This is the offending haircut, by the way: Looks like she wants to be in an early 90s metal band, to me.
I had dreadlocks for around 12 years. But that was because I was a crusty/pikey rather than trying to appropriate any culture.
