Imagine a guy coming in a room, untidy... what is your first impression? The fact is that just with the looks we start to give that person rate, right? It's like..when you are shopping for a 
cool shirt. You won't buy the one dirty and odd looking, you will go for the one that is well presented and well manufactured.
Male grooming is very important, because it reflects your personality, especially to women. If you care enough to maintain hygiene and keep yourself clean and smelling good, they start thinking: "Wow, if he's taking good care of himself, he may as well be good in taking good care of other people".
You don't have to be high maintenance, but you gotta have at least the basics covered. Here are some points to take in mind:
Learn to shave your face properly, stay away from facial hair like beards & moustaches, and other parts of your body, they are only attractive to the minority.
Learn how to choose a good deodorant, because they're not all created equal... in fact, some are twice as effective as others.
Learn to select the appropriate shampoo and conditioner according to your hair texture
Keep your breath fresh, learn how to eliminate the cause once and for all (and no, it's not as simple as brushing your teeth twice a day)
Discover what type of skin you have. This is important because not every skin care product suits everyone. In fact, all the skin care products specify the type of skin they cater too.
Keep your skin moist at all times. Don't let your skin get dry. Dryness causes the outer layer of your skin to break, leading to a rough and unattractive appearance. Use moisturizers/ emollients. Moisturizers work best when applied while the skin is still slightly wet.
Avoid the use of soap on your face. Soap should only be used from below the neck.
Use sunscreen to protect yourself from sun's harmful UV radiations in order to prevent skin cancer caused by them. You can use a moisturizer that combines sunscreen with the moisturizing effect. Use them even when it's cloudy.
Treat skin dilemmas with care. Don't ignore them. Consult your dermatologist before you go on to use any skin care product
