in a phase I/II trial in male pattern baldness" *.pdf from the Histogen Website. A convincing side by side comparison should of course always be from the same region of scalp. I brought the images into PhotoShop and created a new transparent layer over the top of the image on the left. Next I placed green, 3 pixel dots over the hair shafts at the point they exit the scalp. Next I created a purple circle over the red dye originally on their photo. I used the duplicate layer function and created an exact copy of the transparent dot layer. Next, I moved the dot layer using the shift key (to preserve alignment) from over the top of the left (baseline) image to over the top of the (right) 3 month result photo aligning the purple circle over the red dye dot. The dots as you can see, don't align with the hair shafts emerging from the scalp. Note the hair direction is different as well!!! To be fair, I rotated the image on the right to simulate the baseline hair direction under the transparent layer. I used the "Again" command to rotate the transparent green dot layer into the exact position of the rotated scalp image below. I was still unable to align the dots in any reasonable way. I even tried moving the dot layer around every which way to see if there was any pattern of alignment to be found. There was not. One would think in a fair before and after comparison photo, a dye spot on the "before" image, would indicate the identical region of scalp on the "after" image. In other words, what good is a comparison between two different regions of scalp? Hair density and caliber would of course be different from region to region.
