Question

Which one of the following is the reason for increased hair loss during old age?

• A. Reduction of blood supply
• B. Decrease in protein synthesis
• C. Low energy production
• D. None of the above

Answer 1

Answer: (D)

None of the above

Hairs, which must be replaced periodically, grow more slowly in old age, and some hair follicles stop producing new hair. As a person ages, the growth rate of hair decreases. This happens because the follicles do not allow for hair growth as quickly. When hair is growing, it does require a significant amount of blood flow. Therefore, a decreased blood flow to the scalp is not the cause of hair loss, but a result of it.
