- Alopecia areata (AA) is an autoimmune condition that leads to hair loss, influenced by genetic and environmental factors, with recent studies suggesting that scalp microbiota may affect its progression through inflammatory responses.
- A study with 24 participants analyzed the scalp microbiomes of those with varying severities of AA and healthy individuals, finding significant differences in microbial communities and their correlation with inflammation and AA severity.
- Results showed that patients with severe AA had more pro-inflammatory bacteria, while those with milder forms had beneficial bacteria, indicating that scalp microbiota might be linked to AA inflammation, though further research is needed to understand the exact relationship.
