From the study:
Microneedling procedure
The shaven scalp was prepared with betadine and normal saline. A dermaroller of 1.5 mm sized needles was rolled over the affected areas of the scalp in a longitudinal, vertical, and diagonal directions until mild erythema was noted, which was considered as the end point of the procedure. All patients were instructed not to apply Minoxidil on the day of procedure and to resume its application only 24 h after the Microneedling procedure.
