A Six-Month, Randomized, Double-Blind, Placebo-Controlled Study Evaluating the Safety and Efficacy of a Nutraceutical Supplement for Promoting Hair Growth in Women With Self-Perceived Thinning Hair.

What Was Tested

This randomized controlled trial looks at Copper (Supplement).

The objective of this 6-month randomized, double-blind, placebo-controlled study was to assess the ability of this oral supplement (Nutrafol® Women's Capsules) to strengthen and promote the growth of hair in adult women with self-perceived thinning.

Why It Was Studied

There were no reported adverse events.

Who Took Part

PubMed indexes the participants as young adults, adults, middle-aged adults and older adults, women only.

Enrolled subjects were randomized to receive active treatment (n=26) or placebo (n=14).

How the Study Was Run

The researchers set it up as a randomized, double-blind and placebo-controlled study.

Because people in this Copper (Supplement) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

As a double-blind Copper (Supplement) study, the assignments were hidden from both participants and investigators until the end.

The comparison arm used a placebo, so changes seen with Copper (Supplement) could be set against what happens without it.

What Was Measured

The subject headings attached to it are Alopecia, Antioxidants, Dietary Supplements, Plant Extracts and Surveys and Questionnaires.
