Outcome Measures

Primary Outcomes (4)

  • Assessment by digital images for effectiveness

    A photographic review of the scalp for each patient. Photos were standardized as to subject, area, distance, illumination, angle of exposure and background so that there were no major differences between any of the series of photographs. Photographs were taken using Nikon D3300 AF-P 18-55 VR 24.2 Megapixels® digital camera, based on the grading suggested by Olsen et al.,(2002) graded the photographs on a 7-point scale from dense, moderate, minimal growth, no change, minimal, moderate or dense loss. This was shown at baseline and 16 weeks of the trial.

    4 months

  • Trichoscopic assessment for effectiveness

    Images were taken from fixed points in the scalp using the Dermlite П PRO HR® dermoscopy for each patient when they first presented and every month for four months. Digital images of the dermoscopic features were taken by digital camera Nikon D3300 AF-P 18-55 VR 24.2 Megapixels®. The reference points are set to the top of the vertex and a landmark for each frontal region was the intersecting point between lines passing through the ipsilateral tragus and lateral point of eyebrows. Each point was analyzed before and after follow up period by single-blinded expert in trichoscopy looking for the following parameters; total hair count, terminal hair count, vellus hair count, triple or more follicular unit, double follicular unit, single follicular unit, number of perifollicular halo (peripilar sign), thick terminal hair and thin terminal (intermediate) hair. Parameters recorded numerically then statistically analyzed for comparison between different groups of trial.

    4 months

  • Patient satisfaction towards treatment outcome.

    Patient satisfaction scaled from 0 if unsatisfied, 1 is mild satisfied and 2 if satisfied and compliance with treatment was documented through a patient-filled questionnaire.

    4 months

  • Side effects towards treatment used in trial.

    Side effects of the drugs (irritation, dandruff, and hypertrichosis for minoxidil plus nausea for NAC) were documented and statistically analyzed for comparison between groups of trial.
