2. You Use Your Disposable Razor for More Than a Week
Yes, we’re serious—you need to toss it once a week if you’re shaving every single day. “Dull blades are more likely to cause razor bumps, irritation, nicks, and cuts, and old blades can harbor bacteria, which can lead to infections,” says Schlessinger. If you want a closer shave with the least amount of irritation, pay close attention to how many days your current razor’s racking up. “A good rule of thumb is if you feel like it’s tugging at your hair or skin, toss it—it’s most definitely a ticking time bomb waiting to irritate,” says Dendy Engelman, M.D., a dermatologist at Manhattan Dermatology and Cosmetic Surgery in New York City.
