I wish I had that much hair, though I'm glad I'm not diffusing in back.
My hair looks different under the same conditions, same light, etc, on different days. Just depends on hair angle and my standards that day. Very confusing. I stopped looking. I just take my treatments and hope they work.
I was thinking the same thing when I looked at and thought about my baseline and 4 month pics.
I took my first pics with the hair about 3/4 long on top. That has got to be about the worst length for me to take pics. I wish I'd picked a longer or shorter length for the baseline. My 4 month pics were taken with the hair 1 1/2 inches long on top. Even if I used nothing the 4 month pics would have looked better. I didn't mean to take pics like that, that's just the way things turned out.
Changes in flash, lighting, or head tilt can make a big difference also.
I assume everyone's being honest, unless they are trying to sell something.
...and besides, why would anyone want to fake success anyway? I'm sure I could live without the approval of the users of this forum. I'd only be cheating myself, and.... um... if I faked success, then no amount of compliments or congratulations would mean anything to me, because I'd still be a bullshitter...
