1) Cut your nails!!! you have no idea what a turn off is a man with long and dirty nails.
2) Shave. Girls like a man with smooth, clean face.
3) Cut your hair. Especially if you are balding. Persisting on growing your hair only makes thinning hair look even worse than it has to.
4) Shower and deodorant. Shower every day and using a deodorant is a must!
5) Perfume - don't. This may come as a surprise to you, I know, but people react differently to different fragrances. So even if you are using a perfume don't kill your date by spraying the whole bottle on yourself.
6) Smooth hands. Well, not freakishly baby smooth but consider using a hand lotion if your hands are constantly dry.
