FAQ
Overview
Here you will find answers to frequently asked questions about TrichoScan. The topics range from general basics and practical application to its use in studies.
General
What is TrichoScan?
TrichoScan is a method for the objective analysis of hair characteristics. It uses high-resolution images of a small scalp area that are evaluated with software support.
What is measured?
Different parameters are determined depending on the program version. These include, among others, hair density, hair thickness, hair brightness, and the ratio of growing to resting hairs.
Is TrichoScan painful?
No. The examination is non-invasive and usually painless.
How long does a measurement take?
The actual image capture and evaluation usually take only a few minutes. Depending on the case, some additional time may be needed for preparation and documentation.
How meaningful are the results?
A single measurement initially provides only a snapshot. Comparison over time is especially meaningful, because changes can then be recognized and interpreted more reliably.
Can TrichoScan make a diagnosis?
No. TrichoScan is used for the standardized analysis and documentation of hair parameters. It does not replace a medical examination and is not intended for diagnosis or treatment decisions.
For users and providers
Which devices are required?
A compatible dermatoscopy or camera system is required, along with the appropriate TrichoScan software or system environment for evaluation.
How important is standardization?
Very important. Results over time are meaningfully comparable only if images are captured as far as possible under the same conditions.
What should be considered during image capture?
Key factors are a clearly defined measurement site, sharp images, suitable lighting, reproducible magnification and consistent hair preparation.
What are typical sources of error?
- different measurement sites
- blurred images
- insufficient hair preparation
- changed lighting conditions
- non-reproducible magnification
Why is using the same measurement site so important?
Even small deviations can reduce comparability. For follow-up measurements, it is therefore crucial to relocate the same scalp area as precisely as possible.
How can results be explained clearly?
Best with simple statements and over time, for example: more or fewer hairs, rather thicker or finer hairs, and visible changes between several measurement time points.
Is hair preparation required for every measurement?
That depends on the version and system used. Depending on the workflow, hair preparation may be necessary, while in newer solutions certain steps may be simplified or omitted.
For studies and research
What is TrichoScan suitable for in studies?
TrichoScan is suitable for the objective capture and documentation of hair parameters, especially for observing changes over time.
Which version is used for studies?
The research version, TrichoScan Research, is intended for studies.
Can TrichoScan be used as an endpoint?
Yes. Depending on the study design, different hair parameters can be used as endpoints, for example hair density, hair thickness or the ratio of anagen to telogen hairs.
What role does reproducibility play?
A central role. Standardized workflows are essential so that results remain meaningfully comparable between time points, examiners or study centers.
How is quality ensured in studies?
- standardized imaging conditions
- clear SOPs
- documentation of the measurement parameters
- appropriate training for the users involved
Are custom parameters possible?
Depending on the question, project-specific parameters may be relevant in addition to standard metrics. Whether and how these can be implemented depends on the respective study context.
