Did you know that a single strand of human hair is strong enough to hold up to 100 grams of weight? That means if you gathered all the hairs on your head and tied them together, they could hold up a small car! The strength of hair comes from the protein keratin, which is also found in nails and animal hooves. So next time you're tempted to pull out a hair in frustration, remember how strong they are!
