Summarize the following:
You can use the same trimmer you use for your beard to save money or you can purchase a new one. Since it’s very easy to clean trimmers—both electric and non-electric—this is really a matter of preference. There are a variety of electric clippers—both with and without cords—available online and in stores. Most electric clippers come with guards. Another option is to go with a non-electric trimmer to avoid the hassle of plugging in or charging your trimmer. The Gillette power fusion razor and trimmer is a non-electric option that can be purchased in stores and online and it comes with guards for setting the length. Guards are the attachments, also known as spacers, that can be affixed to the clipper or trimmer to determine how much hair the trimmer or clipper will leave uncut. Guards should come with the trimmer and most trimmers come with guards ranging from 1/8 inch to 1 inch. If you’re cutting off a lot of hair, you may want to avoid trimming in the bathtub, as this could clog the drain. One option is to spread out towels on the bathroom floor to collect the hair. Another option is to simply trim your hair in an area that is easy to sweep. If you have access to a private space outdoors, consider trimming your hair outside to avoid having to clean up. If you do trim your hair in the bath tub, a damp paper towel can be used to collect the hair from the sides and base of the tub so you can dispose of it in the trash to keep it from going down the drain.

Summary:
Choose a trimmer. Make sure you have a selection of guards to choose from. Choose a convenient and private location to trim your hair.
