结论
Viviscal is supported by multiple clinical trials suggesting it may help promote hair growth and reduce shedding in people with age-related hair thinning, though studies have been relatively small.
- 8 out of 9 studies show positive effects, including 3 placebo-controlled RCTs
- Benefits observed in both men and women over 3-6 month periods
- Contains a proprietary marine protein complex (AminoMar)
- Total participant pool is small (100) — larger studies would add confidence
