Does it bother girls if a guy doesn't want to look good? It may bother some gals and it may not bother some gals. I'm of the latter it doesn't bother me if a guy doesn't want to look good as I really don't care what people choose to do to themselves. However I probably wouldn't be interested in such a guy unless he was already attractive without caring about how his looks as to me a guy's attractiveness is pretty much what guys have to offer.
Obviously these girls are very judgmental. I like the guy to present himself well. If you are constantly wearing ripped and dirty clothes and you smell bad ill definitely be turned off. If you don't want to do your hair every single day I'd be fine
