I love this question! this may be a controversial answer but it's just a idea. My parents are Ghanaian and i was born and raised in the UK now living in the US. When my mother was young she wore her hair very short, like Otegwu mentioned, also traditional braided styles have always been popular in 'Africa' (which is a HUGE continent so i hate to say "Africa" in a general way but anyway)
Anyway African Americans have the most visibility world wide (American movies, music and culture have permeated every corner of the world) Maybe she is wrong but my auntie thinks "Africans" have emulated what they have seen inn the mainstream, which is African American culture, straight hair/weaves etc. While i don't know if this is true i must say many of these women that are covering their beautiful hair with raggedy weave MUST have some kinda deep rooted issue with their hair. It makes no sense to me the crap some women throw on their head believing it makes them look more attractive or more presentable than their hair underneath. And believe me, i speak from experience. Growing up i had NO IDEA what to do with my hair, i grew up in a tiny town in England with no other black people literally!!! My mother kept of hair cut low when we were younger, as i got older i wanted length, i would look at American black hair magazines when i visited my aunt in the city and had no clue how i could get my hair to look like the girls in the pictures. I remember the 2 times my mother relaxed my hair as a kid (after breaking a million combs) i was in awe of the little girl on the just for me box, i couldn't believe how straight her hair was, my hair NEVER turned out that way. My mum would do a rollerset (we didn't have a hair dryer) then tell us not to get our hair wet
. Also my sister and i always though Americans must have incredible water that makes their hair grow super long, not know we were looking at women with a ton of weave in their head.
. So i'm saying this to say, i most definitely had issues with my hair and i'm not ashamed to admit that. But with education and self evaluation i realized i had such a skewed view of how i thought i should look. I had a friend who wore an awful awful wig constantly, one day i asked to see her hair underneath and it was severely matted. I was so sad. I tried to help her detangle but we had to cut most of it. The crazy thing was that she had this beautiful head of thick 4a hair that she was so ashamed of.
I think whenever you are a minority you are influenced by dominent culture to some extent (obviously this depends on other factors too). I truly believe black people everywhere have been impacted by slavery (bothe european and trans atlantic) in some way. Yes i am Ghanaian but my ancestors were also slaves. Many blacks in the UK have been misinformed, there has been a significant African presence in the UK for hundreds of years BEFORE slavery, but they like to tell us blacks came to the UK as slaves and in the 40s with the windrush. Anywho there is definitely a large Jamaican community in the UK (more Jamaicans/people of Jamaican descent in the UK then anywhere else in the world including Jamaica!) There are many other carribean communities and a ton of African communitys. Anyway, history lesson over
....i just realized i just wrote a ton of stuff that has nothing to do with OP's post! My bad
