Moustaches
If you want to keep a moustache, first see which one will suit you. You must experiment but first see whether a Wario will suit you or a Ringo or Stalin, choice is yours.
Haircut
Just don’t follow the fashion blindly. Everyone has a different face cut and should get their hair trimmed as per the face cut. First see, whether you have an oval shape or a round one.
Groom as per your profession
You have to see the kind of profession you are in and then decide what will look the best. For instance, a man in food service won’t look good with a full-grown beard or a soul patch won’t look good in white collar job.
Grooming products
Don’t use just any cream or moisturiser. Go shopping for yourself and buy good grooming products. Look for hair gels, after-shave creams, perfumes, hair spray, etc and style yourself.
