If someone says that the strength of human hair is comparable to that of steel, that might sound like an exaggeration. But don’t worry you will see that coming here.
Human hair has the ability to stretch up to 1.5 times its original length before breaking. Scientists and researchers at the University of California San Diego are studying the basic structural and behavioral properties of hair in order to develop materials with the same properties.
During the research, scientists discovered that the strength of a hair is determined by how fast or slow it was pulled. For example, if a strand of hair is stretched slowly, it breaks easily. On the other hand, if it is stretched fast, it becomes stronger and does not break off easily.
The reason for this has been attributed to the cortex fibrils and matrix, the main parts of the human hair. Cortex fibrils comprise thousands of keratin proteins that wrap around each other like a chain.
There are thousands of such chains that give hair its strength. In the case of an average person, the hair on their head has the ability to support a full grown woman. Furthermore, when pushed to its limits, a full head of hair can lift 12 tons, which is the same as two elephants!
