Scalp's Unique Microbial Ecosystem
- Your scalp's microbial ecosystem is dominated mainly by two bacteria: Cutibacterium acnes and Staphylococcus epidermidis.
- These microbes secrete antimicrobial peptides, protect follicles, and regulate inflammation efficiently.
Effects of Scalp Dysbiosis
- Dysbiosis disrupts your scalp's microbial balance, triggering inflammation and symptoms like greasiness and itching.
- This leads to weakened hair follicles, increased shedding, and a cycle of irritation.
Biological Factors Affecting Scalp Microbes
- The scalp's oily environment and thick hair create ideal conditions for fungus like Malassezia to thrive.
- Genetic and climate factors also influence microbial balance by affecting follicle and pH characteristics.
