How often will you be using it?
If you are shaving your head every few days, it’s better to get a more heavy-duty clipper.
How much do you want to invest?
Generally the more you spend, the more reliable the equipment, but no matter what your budget, do your research ahead of time and read up on the models you’re considering.
Are you planning to use it on your beard as well?
If so, opt for something with added extras, like a beard comb, or that states it can be used for personal grooming as well as on your head.
How short do you want your hair to go?
Shaving all over is one thing but, if you want to recreate a barber-cut short back and sides at home, you’ll need a guarded clipper.
Do you want mains powered or cordless?
If you do your grooming in the bathroom, cordless is your best bet. Opt for mains powered if you’re always forgetting to charge your devices.
