Nutrafol Women,
does it really help with Hair growth in women with self-perceived thinning hair?
research showsThe grade is C with 46 points. In a 40-person randomized trial, the registered day-180 terminal- and vellus-hair counts both favored Nutrafol, and all six comparisons after the paper added day 90 and total hair were significant. Evidence is limited to one manufacturer-funded, very small trial, and the paper broadened the primary endpoints beyond the registry.
ads claimThe trial evaluated a finished four-capsule product combining botanicals, marine collagen, vitamins, and minerals. It does not isolate one ingredient as the cause of hair growth.
Useful facts when choosing a product
- Participants took four capsules with a meal daily for 180 days.
- The product combined proprietary Synergen Complex with hydrolyzed marine collagen, hyaluronic acid, kelp, vitamins, and minerals.
- The manufacturer and seller, Nutraceutical Wellness, provided the financial support.

What the research actually shows
One center randomized 40 women, 26 to Nutrafol and 14 to placebo, for 180 days. The registry states that a nonparticipating employee prepared the randomization table, subject numbers were assigned from it, and blinding was maintained until study completion. The paper reports the 26/14 groups but gives no transparent completer flow or missing-data method, and denominators vary for some secondary outcomes. Nutraceutical Wellness fully funded the study; coauthor Sophia Kogan was a company researcher, and Glynis Ablon received a study grant.
Why this is classified as C (46)
Registered day-180 hair counts were positive, but magnitude on this objective morphologic surrogate cannot be judged; one 40-person manufacturer-only trial and broadened primary-outcome reporting give C with 46 points.
Counterpoint. People who are pregnant, have thyroid or hormone-related conditions, or take multiple medicines should review the full formula with a clinician.

| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I0 | Evidence comes only from manufacturer studies |
| Effect size | EX | The clinical size of the effect could not be judged |
| Precision | CX | No pooled confidence interval could be confirmed |
Stored derived and displayed grades match; this is not a current recalculation or validity check (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Nutrafol increases hair counts at 180 days | C | Both registered terminal- and vellus-hair counts favored Nutrafol. |
| Nutrafol improves quality of life | D | The total quality-of-life score was not significant. |
