Nicole,
As SMP is something that I am researching I revisited this thread as my crazy mind will tend to over analyze things...Most of us will agree that without question the SMP has definitely provided an illusion of better density due to limiting the contrast, but is there an actual odd hue in the crown region or a lighting issue? Sorry to get overly picky but of course this forum is about transparency.
The more I actually studied the photos it looked to me like he had a rather weird color to the crown that stood out as different?? Am I seeing things? Was just the thinning areas done or most of the scalp??
