I think that R&L started to really show/try more African inspired hair and fashion. But it is behind a paywall, and more formal aimed. I find some of these hairs very gorgeous.
I admit there are a lot of straight haired assets that even have similar versions cross pack, bloating the straight hair category. I have too many hairstyles for my main, that I can't even use all the ones I like. So the imbalance is obvious.
Plus, I do think there are a distinct difference between North American African-American styles, and regional/cultural African styles.
