I got this to accompany my nerdy Spock movie costume, and it definitely does the trick. This comes with a wig cap that you will likely want to replace, as it is flimsy and has large gaps (but still technically works). This is actual fake black hair, not the molded vinyl "spock wig" that they also sell on Amazon. It does not come with ears.

Poofed up, it's a little large. I'm a tall person, and it was pretty large on my head. Perhaps it needs some product to tame it, wild beast that it is.
