Quizplus · Accepted Answer

Disulfide linkages and hydrogen bonds are molecular forces that hold hair strands together, while nonpolar hydrocarbon tails are not. Nonpolar hydrocarbon tails are part of the structure of the fatty acid layer that surrounds and protects the hair shaft, but they do not contribute to the molecular forces that hold the hair strands together.
