Final answer:
Removing vellus hair can negatively affect the body's ability to maintain homeostasis by disrupting temperature regulation, protection against pathogens, and proper functioning of sweat and sebum production, possibly exacerbating age-related changes in skin health.
Step-by-step explanation:
The negative effect of removing vellus hair includes potential disturbance to the body's homeostasis. Vellus hair, although fine and colorless, plays a role in regulating body temperature and also in providing some measure of protection for the skin. Possible consequences of vellus hair removal may include increased susceptibility to skin damage due to lack of protection, inability to effectively regulate body temperature, and potential alteration of sweat production.
Furthermore, vellus hair removal could lead to a decrease in the barrier against pathogens and a disruption of sweat and sebum production. As a person ages, there's already a natural reduction in these functions, and vellus hair removal could amplify these age-related changes, affecting the overall health and condition of the skin.
