This study developed a new semiquantitative grading scale for frontal and vertex androgenetic alopecia, which was found to be more sensitive and objective than existing classifications.

A new reliable scale improves accuracy in measuring hair density and treatment response.

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.

This study found that topical 0.05% betamethasone dipropionate was the most effective treatment for patients with patchy alopecia areata, with less than 25% hair loss, over a 12-week period, compared to other topical treatments.

In this study, injecting two different concentrations of botulinum toxin A was found to be safe and effective for treating androgenetic alopecia in Egyptian men and women, with improvements in hair grade and vellus hair density observed over six months.
