Assertion is true but reason is false.
Explanation:
- Hair has two part; shaft and root.
- At hair shaft there is no blood supply and there is no nerve cells. Moreover hair cells are mostly dead cells.so, we does not feel any pain during hair cutting.
- There is a blood supply to the root of the hair. Root of the hair also contain sensory nerve. therefore we fell pain when hair is pulled.
- Therefore the assertion is correct that you do not get hurt when you get a haircut but reason is false because root of the hair have sensory neuron.
