Single human hair strand can hold up to 100 grams

Hair is surprisingly strong material and a single hair strand can hold up to 100 grams. The combined hair of the whole head could support 12 tonnes (that's about the weight of two elephants). The strength of a hair can be compared to the strength of aluminum/aluminium, reinforced glass fibres or kevlar, which is used to make bulletproof vests.

You can test your own hair strength by following this cheesy instruction video:

Most common interest in hair is focused on hair growth, hair types and hair care, but hair is also an important biomaterial primarily composed of protein, notably keratin, which is also the key structural component of nails, horns and the outer layer of human skin. Keratin is one of the main reason that makes our hairs grow, it also provides structural integrity and toughness to the hair shaft.
