In this study, a modified Sinclair scale was presented for evaluating hair loss severity in men with female pattern hair loss, outlining stages from normal hair density to severe hair loss while preserving the anterior hairline. Reliability data for using this scale was also included.
April 2026 in “Zenodo (CERN European Organization for Nuclear Research)” In this study, Dodatek A operationalizes the Functional Androgen Axis framework by defining three system-level indices and an efficiency metric to describe androgen function, incorporating key methodological improvements and acknowledging significant limitations for future empirical validation.
June 2024 in “British Journal of Dermatology” This study found that alopecia areata significantly impacts patients' quality of life irrespective of hair loss severity, and concluded that the newer assessment tools AAPPO and AASIS better capture this impact compared to the traditional SALT measure.
June 2024 in “Nature Cell and Science” In this research, experienced clinicians noted inconsistency in the reproducibility of the commonly used Hamilton-Ludwig scales for assessing pattern hair loss severity in photographic assessments, leading to the proposal of a new 5-point scale for staging female hair loss.

December 2017 in “Journal of Investigative Dermatology Symposium Proceedings” This article presents a computer imaging algorithm that may automate and enhance the Severity of Alopecia Tool scoring for alopecia areata through texture analysis of pediatric images.
July 2025 in “International Journal of Cosmetic Science” In this study, researchers developed a new 6-point scale for evaluating heat damage to hair from straighteners, finding a strong correlation between technical damage measurements and human perception of hair damage.
June 2020 in “Journal of cosmetic medicine” This article discusses the development of a standardized assessment scale for hair transplant outcomes, emphasizing multiple parameters that contribute to an aesthetically pleasing result and reports no new clinical findings.
In this study, centralised measurements provided more consistent and accurate results for assessing hair loss in mild-to-moderate alopecia areata, reducing error compared to local ratings.
September 2022 in “Journal of Investigative Dermatology” This study found that the Severity of Alopecia Tool score does not predict the quality of life in patients with alopecia areata, suggesting patient-reported outcomes better reflect the impact on life quality.
August 2024 in “Frontiers in Public Health” In this study, researchers developed and tested an Italian version of the Skindex-16AA to assess Health-Related Quality of Life in patients with moderate-to-severe Alopecia Areata, emphasizing the importance of patient perception in evaluating their mental health and quality of life.

June 2021 in “Journal of The American Academy of Dermatology” This correspondence reports that some men with androgenetic alopecia can exhibit hair thinning patterns more typical of females, with variations observed between Australian and Korean populations.
April 2026 in “Academic Dermatology” In this retrospective observational study, researchers found that the Dean Scale showed better diagnostic accuracy than the CTCAE scale for detecting clinician-reported therapeutic responses to minoxidil in patients with anticancer therapy-induced alopecia, but both scales had limitations in recording clinically significant hair regrowth.
