Ace the 2025 PSI Barbering Exam – Snip, Style, and Success Awaits!

AIDS, or Acquired Immunodeficiency Syndrome, is fundamentally a condition that severely compromises the immune system. The immune system is responsible for protecting the body against infections and diseases. When an individual is infected with the Human Immunodeficiency Virus (HIV), which leads to AIDS, it gradually destroys the CD4 cells, which are essential for maintaining a robust immune response. As these cells diminish in number, the body becomes increasingly susceptible to infections and certain cancers, resulting in the defining characteristics of AIDS. It is crucial for anyone studying for the PSI Barbering Exam to understand how conditions like AIDS affect overall health, as this knowledge may inform their practice, especially in terms of maintaining a hygienic environment and understanding client care needs.

The other systems listed—nervous, digestive, and respiratory—do not play the central role that the immune system does in relation to AIDS. While they can be affected indirectly due to the overall health and immune status of the individual, it is the immune system that is directly targeted and undermined by HIV.
