Quizplus · Accepted Answer

Hairs grow from cells in the matrix of the root that are still undergoing keratinization, which is the process of converting protein into the tough fibrous protein called keratin. As the cells undergo keratinization, they push previously formed cells upward, which results in the continuous growth of the hair shaft.
