En conclusion
Research does not support keratin supplementation as helpful for telogen effluvium — the limited evidence available suggests it is unlikely to meaningfully reduce this type of hair shedding.
- Majority of studies show negative or no effects for keratin in telogen effluvium
- Very small participant pool (60 people) limits the reliability of findings
- Telogen effluvium has different underlying mechanisms than age-related thinning, where keratin shows more promise
- Other approaches may be more effective for addressing telogen effluvium specifically
