Dear Doctor Rassman,
In your juvenile hairline post I noticed something. In all pictures you used overhead harsh lighting. Therefore you see scalp in the juveile hairline of the woman and the man, and in the mature hairline of the handsome lad ;), with hair that is combed back.
Is it normal to be able to see some scalp at the juvenile frontal hairline under harsh lighting? Is this what we call a transition zone?
I must compliment you on the honest pictures used on your site and blog. Amazing results! Keep up the good work with your blog.
Yes, you are on target with your thinking. Everyone has a see-through transition zone… and under harsh lighting more scalp will be visible.
