निष्कर्ष
Keratin supplements show good evidence for supporting hair growth in age-related thinning, with multiple RCTs reporting positive results, though the research includes a mix of direct and indirect evidence.
- 21 out of 32 studies show positive effects, including 5 randomized controlled trials
- Annurca apple-derived keratin formulations have shown particularly promising results in RCTs
- Keratin-related signaling pathways are well-established as important for hair follicle health
- Some evidence is from laboratory studies, so real-world effectiveness may vary
