What must be true for hair to continue growing?

1. The follicle must be nourished

2. The papilla must be alive

3. The hair must be treated regularly

4. The scalp must be clean

The correct answer is: The papilla must be alive

For hair to continue growing, it is essential that the papilla, which is the small, bulb-like structure at the base of the hair follicle, remains alive. The papilla contains blood vessels that supply nutrients and oxygen necessary for hair growth. When the papilla is intact and functioning, it enables the continuous production of new hair cells. This biological process is crucial for healthy hair growth, as it directly affects the hair follicle's viability and its ability to regenerate new hair strands. While nourishing the follicle and maintaining a clean scalp can support good hair health overall, the direct requirement for hair growth hinges primarily on the vitality of the papilla. Regular treatments can also promote hair health but are not as fundamental to the process of hair growth as the presence of a living papilla.
