New Frontiers of Non-Invasive Detection in Scalp and Hair Diseases: A Review of the Application of Novel Detection Techniques.

OBJECTIVE

The aim of this paper is to review the current status and recent progress of the application of novel non-invasive testing technologies in the diagnosis, treatment, and care of scalp hair diseases in recent years, and to discuss their contribution to the improvement of scalp hair health management.

METHODS

Through a literature review, the principles and current status of application of technologies such as trichoscopy, microbiological testing, scalp skin physiological function testing, hair physiological index testing, and hair product patch testing, and their specific roles in the management of scalp hair diseases were systematically sorted out.

RESULTS

Trichoscopic intelligent analysis technology can quantitatively assess the hair growth status and provide an objective assessment of the efficacy of hair diseases; microbiological testing provides a laboratory reference for the rapid diagnosis of scalp diseases and clinical use of medication; scalp skin physiological function testing and hair physiological index testing are essential for a comprehensive assessment of the scalp environment and hair health. The patch test can effectively detect allergenic substances, which can help to safely select topical drugs and hair care products, avoid medical risks, and facilitate safety evaluation.

CONCLUSION

Novel non-invasive testing techniques provide powerful technical support for accurate diagnosis, personalized treatment, and safe care of scalp hair diseases, and show a broad application prospect. Future research should focus on improving the accuracy and detection efficiency of these techniques to meet the growing demand for scalp hair health management and to promote the development of this field in a more scientific and refined direction.
