## What The Sources Report

- The largest mean growth effects were localized in posterior terminal hair count, which increased significantly by 13.0 (22.4) at Day 180 for the active group (&#8201;<&#8201;0.001), while the mean posterior terminal hair counts for the placebo group decreased by &#8722;7.6 (18.4). [Ablon Glynis (2026); evidence level 4]
- Serenoa repens Following an analysis of available research data and clinical evidence, a novel, proprietary bioactive fatty acids extract from saw palmetto has been developed for maintaining hair health and treating hair loss (SEREVELLE, formerly USPlus DERM, Valensa International; Eustis, FL). [Ablon Glynis (2025); evidence level 4]
- Assessment at 12&#8201;weeks revealed significant improvements in hair loss and increased hair density in both male and female subjects which began as early as 4&#8201;weeks with an overall high degree of subject satisfaction. [Ablon Glynis (2025); evidence level 4]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation

For saw palmetto hair loss randomized trial, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

## Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
