Quoting Brittany p shelton:" Okay so me and my BD broke up about 3 months ago. He treated me like the lowest piece of crap on this ... [snip!] ... I think this guy is an amazing person and like i said, he looks amazing. But I need some insight!!! What does everyone think?"
In my experience if I guy notices your hair, he is either gay, or into you
Add in the bit about wanting to "sleep" with you, I'd say he is definately into you lol. As the ladies above me said, not sure if he just wants to get some, or if he really
likes you though. I would just keep flirting with him, and hangin out untill he asks you on an official date.
