Don’t pluck gray hair!
Yanking out a renegade gray won’t cause two or ten more grow back—total hair myth. When a strand grows gray, it means that specific hair follicle is producing less melanin, a pigment that gives hair its hue. Plucking it isn’t going to magically summon the surrounding strands for revenge, but it may cause some trauma to the follicle. And when it grows back gray—because it always will—pulling it out again and again may lead to infection or scarring of that hair follicle. Color it, cut it if you must, but stop plucking. You should never, ever touch these parts of your body.
Don’t pick a hangnail!
It’s the skin near the nail—not the actual nail—that’s doing the hanging, and it’s crazy how such a tiny piece of torn skin can hurt so much. The last thing you want to do, though, is bite, chew, or rip it off. Bacteria can then infect the open wound, making it red, swell, and throb. Instead, cut the extra skin with a clean nail clipper or small nail scissors, dot it with antibiotic cream if it’s red and sore, and cover it with a bandage for a few days until it heals.
