I changed my hair and bought a new shirt today but I still don't have a gf or get any luck with the ladies

I’m a 20 yr old with a beard and a decent hairline. I’ve changed my hair 3 times now and wore 5 new shirts just to get a gf. Every saturday I try my luck to go outside to get a gf. I lost 30 pounds 3 months ago but changed my hair 3 times since then just to make sure but I’m still getting 0 luck. I’m curious, is it possible for a guy to not get a gf no matter how hard they try? I just want a wife and kids but I seem to be rejected not matter how much I change my appearance. What’s happening?
