Did You Know!
Human hair is made primarily of keratin, a protein that also forms the structure of fingernails and animal hooves. A single strand of hair can support up to 100 grams (3.5 ounces) of weight. Considering an average scalp has about 100,000 to 150,000 hair follicles, the combined strength of all the hairs on a person’s head could theoretically support the weight of two adult elephants!
