A Hair parameters were assessed using Fotofinder® medicam 1000 s video-trichoscopy (2) at the meeting point (1) of the highest part of the ears and the medial aspect of each eyebrow (indicated by red “x” marks) on both sides of the scalp. The findings were available for immediate viewing on a computer linked to the device (3). B After the administration of lidocaine cream, the scalp was divided into two parts. The placebo was applied to one side of the scalp and the treatment solution was to the other. Intradermal injections were given at 1 cm distances from the temple to the crown (hatched in blue and green lines)
