You need to determine if these are real people or bots, where they're from, and what they're actually looking for. If you can do that, you might be able to make a couple bucks, but 2000 visitors for something like "curly hair" isn't the most valuable traffic in the world... Are they looking for tools to curl their hair? Do they just want to see pictures of people with curly hair? Do they need shampoo recommendations?
For example, that 2000 visitors could be worth nothing, it could be worth a couple bucks if they're looking for photos, it could be worth a lot if they're looking for world-class education on how to curl hair professionally at the highest level...
So, pop up a quick lil site, and find out
Either way, 2000 a month won't make you a heck of a lot of a kw like "curly hair", so are you willing to use that as a head start to build a website that gets 20,000 per month? 200,000 per month? At that point, it could probably cover your rent. But if you are willing to develop it to 200,000 visitors per month, how much is that 2000 head start really worth, should that be the thing that dictates which niche you choose...?
