INTRODUCTION: HAIR MASS INDEX (HMI): Distinguish “patterned” hair loss vs. diffuse Assess hair growth changes over time For a physician or patient, the quantitative evaluation and tracking of changes in hair growth Establish baseline data Improve patient compliance can be a challenging task. Current methods are fraught with inaccuracies and inefficiencies. Track treatment-response Improve medical management outcomes For example, global patterns of scalp coverage provide little information on the degree of miniaturization, a hallmark of early hair loss, or a patient’s subtle response to treatment over time. Even in the most controlled photo studio environments, standardized global photography can be inconsistent due to changes in hair length and styling. Video magnification of the scalp (40-200x) and hair count densitometry provides additional CONCLUSION: The implementation of any new diagnostic tool requires an investment in time, effort, information and raw data, but also have limitations including having to trim hair to obtain personnel and other resources. Each physician must make his own judgment whether accurate measurements as well as equipment costs. these investments are “worth the return” of the benefits received in terms of patient care. In our opinion, hair bundle cross-section measurements have provided us and our patients “Cross-Sectional Bundle Trichometry” is a patented, scientifically accurate, repeatable non- with easily understandable clinical information within minutes that was previously not invasive method of measuring the cross-sectional area of hair (Hair Mass Index or HMI) in a attainable. predetermined area of scalp. A patient’s HMI measurements can be accurately obtained in minutes by a physician or another staff member without the need to trim hair. For example, during this initial trial period we were able to detect and quantify non-visible thinning in male patients with early balding and quickly differentiate diffuse from pattern In a hair loss patient, comparing HMI between various areas of scalp can yield valuable balding in females with hair loss. We have able to track patients with thinning, telogen diagnostic information. Comparing HMI measurements obtained in the same area of scalp Sample of an HMI report effluvium, and we were able to critically evaluate our patient’s response to minoxidil, over time allows the quantification of subtle hair growth changes such as the progression of Two technicians obtaining and provided to a patient. finasteride, dutasteride, low level laser therapy and nutritional modification in a shorter hair loss or response to treatment.
