TrichoScan is a modern, digital method for analyzing hair growth and diagnosing hair loss disorders. It is a non-invasive technique that allows for a detailed examination of the scalp and hair by analyzing digital scalp images with specialized software. This method combines epiluminescence microscopy (dermoscopy) with digital image analysis to quantify various parameters of hair growth, such as hair density, hair thickness, growth rate, and the ratio of anagen (growing) to telogen (resting) hairs.
How the TrichoScan works
- Preparation : A small area of the scalp is shaved and marked with a special dye that enhances the contrast of the hair follicles . After a few days, during which the hair can grow back somewhat, high-resolution images of this area are taken.
- Image acquisition : The images are taken with a high-resolution digital camera connected to a dermatoscope. This allows for a detailed examination of the scalp and hair follicles.
- Analysis : The captured images are analyzed using specialized software to measure various parameters of hair condition. The software can distinguish between hairs in the growth phase and those in the resting phase, thus enabling an accurate assessment of the hair loss pattern and hair density.
Applications of TrichoScan
- Diagnosis of hair loss : The TrichoScan helps in the diagnosis of various forms of hair loss, including androgenetic alopecia , alopecia areata and telogen effluvium.
- Assessment of treatment effectiveness : It is used to evaluate the success of hair growth therapies by taking comparative measurements before and after treatment.
- Research : The TrichoScan is also used in clinical research to test and develop new treatments for hair loss.
Advantages of TrichoScan
- Non-invasive : The examination is painless and does not require the taking of hair or skin samples.
- Fast and efficient : The analysis delivers quick results and allows for an accurate assessment of the hair condition.
- Objective : Digital image analysis offers objective and repeatable results that are less subject to subjective interpretation than manual examinations.
Limitations
- Costs : The costs for a TrichoScan can vary depending on the provider and are not always covered by health insurance.
- Availability : The technology may not be available in all dermatological practices or clinics.
Overall, the TrichoScan is a valuable addition to the diagnosis and treatment of hair loss disorders, enabling a precise and detailed analysis of hair growth.
