Start with the model

Ask whether the result occurred in a dish, a mouse, human skin grafted onto a mouse, or a treated person. Each can be scientifically valuable, but they answer different questions. A humanised mouse model may demonstrate hair induction without proving scalable manufacturing, surgical placement or long-term safety in patients.

Identify the endpoint

Hair shaft formation, increased shaft diameter, photographic improvement and counted terminal hairs are not interchangeable endpoints. Stronger claims report predefined measurements, a comparator group, blinded assessment and follow-up long enough to observe durability.

Look for traceable evidence

A registered trial record, peer-reviewed paper and regulator-reviewed protocol provide different levels of visibility. Company announcements are useful primary sources for what a developer claims, but they are not independent confirmation. We label source type and avoid converting development intentions into forecasts.

Check regulatory status

Being listed on ClinicalTrials.gov does not mean a product is approved. In the United States, the FDA warns that regenerative products marketed outside appropriate approval or oversight can pose serious risks. Similar distinctions apply in other jurisdictions, even when a treatment uses a patient’s own cells.
