This exploratory study evaluated the effects of a red clover-chamomile complex extract ampoule on hairline hair density, hair shaft thickness, and product usability in 10 participants over 4 weeks. Results showed a significant increase in hair density by 49.5% and hair shaft thickness by 80.7%. Usability scores also improved significantly, with no adverse events reported. The findings suggest that the ampoule effectively enhances hairline characteristics and is safe to use, though further randomized controlled trials are needed to confirm these results.
