Question: 1 / 400

What is the primary function of the scalp?

To store nutrients for hair growth

To protect the skull and provide a foundation for hair growth

The primary function of the scalp is to protect the skull and provide a foundation for hair growth. The scalp acts as a barrier, safeguarding the underlying structures of the head, including the skull and brain, from environmental elements and potential injuries. Additionally, the scalp is an essential part of the hair growth cycle. It contains hair follicles, sebaceous glands, and blood vessels that supply nutrients and oxygen to the hair. This foundation supports the development of healthy hair, making it crucial for overall scalp and hair health.

While other choices touch on important aspects of scalp physiology, they do not capture its primary purpose as effectively. For instance, storing nutrients, regulating temperature, or absorbing hair products are secondary functions that may contribute to scalp health but are not its fundamental role.
