From a business standpoint, posting about things your target market like is always a good thing. For you maybe makeup tutorials, piercing and tattoo care, dread care (both real and fake), pairing hair accessories with outfits, etc.
I try to think about the things my customers are also interested in and just kind of wing it from there. Plus, it makes it really easy to weave a sales call to action into other content that readers are more likely to share.
Hope that helps!
