Official title

Pilot Study to Evaluate the Efficacy and Safety of Xtresse FR Concentrate Serum in Individuals With Self-Perceived Thinning Hair.

The first row holds the registered conditions that placed this trial on the pipeline; the second holds everything else the sponsor registered on the same record. Both are shown, and shown apart rather than shaded differently, because leaving the second out would make this trial look more like a hair-loss study than its registration says it is — and because a distinction carried only by colour is not a distinction for every reader.

What it measures

1. Increase in hair density assessed by Canfield HairMetrix® Phototrichogram Analysis

   Time frame: From enrollment to end of treatment at 4 months

2. Hair Density changes measured by SOCAi

   Time frame: From enrollment to the end of the study at 4 months

3. Increase in hair thickness assessed via Canfield HairMetrix® Phototrichogram Analysis

   Time frame: From enrollment to the end of treatment at 4 months

Primary outcome measures only, as registered. What a trial chose to measure, and when, is the most informative thing about it that is knowable before it reports — a hair-count endpoint at 24 weeks and a patient-satisfaction endpoint at 12 weeks are not the same study.

"Estimated" and "actual" are the registry's own labels: an estimated date is a plan, and plans move. A date is printed at the precision it was registered at: a primary completion registered as 2027-03 is a month, and rendering it as 1 March 2027 would invent a day the sponsor did not register.

Results

This trial has not reported results. ClinicalTrials.gov holds no results record for it. That is the ordinary state of a trial that is running or about to run, and it means there is nothing here to tell you about whether the intervention works — including nothing negative. If this page implied otherwise it would be wrong.
