First, let's step away from this notion of "harsh" truth. I'm not disagreeing with you because I cannot emotionally handle what you are saying. I am disagreeing because the evidence you provided is not that great. That is, it is not very convincing when you provide a few vague pictures (eg. A young Travolta from a 3/4 perspective, compared to a much older Travolta facing square, and shot with a telephoto lens - these are not good for comparison because there are many variables at play) and essentially claim that bald peoples' heads balloon up. Your pictures are not compelling, and additionally, how do you know the same is not true for those who do not go bald? You cannot see their skull shape because the hair is in the way.
Hair is intentionally cut unevenly, rather than conformal with the skull, to give an aesthetic shape, (source: Milady's Standard Cosmetology, the most commonly used text within cosmetology schools in the U.S.) unless you are showing someone who is buzzed down. In other words, hair shape is not a reliable indicator of skull shape. And then there are bald people who have perfectly reasonable or even deficient looking skulls. Not all bald men have big heads. To me it just seems like you just think the bald look is ugly. But let's keep in mind your original claim -
the balding process causes a change in the skull shape, namely by increasing its size/girth. This claim naturally beckons before and after pictures of the same individual and I have shown you why the pictures you provided before are not adequate - the effect of the camera lens totally confounds any growth that may be real.
And no I will not do the work for you by looking up pictures. If you want to prove your point, I am happy to look at pictures you post. For now, what I am seeing are pictures 1) Taken with a telephoto lens and 2) of thick built men or 3) pictures of men with an indentation or other anatomical landmark whenever you want to provide evidence for your skull expansion theory.
What I need from you are pictures of balding people showing that their skull changes over time not due to a telephoto lens, and I require the same of a non balding people showing no such change. For your convenience, I already posted images of a fullhead, Brody Jenner, demonstrating the effect of a telephoto lens. His skull has not grown; the only changes are the camera settings.
I find it more plausible to believe that many people have strange skull shapes sitting right there under their head of hair, but I am open to being shown otherwise.
For kicks, here is a picture of a severely balding man with a much smaller skull shape than the ones you posted (by the way, different ethnicities can have markedly different skull shapes, please take care to not only look at anglosaxen skulls).

And as an additional tidbit, I personally happen to have a skull shape similar to that of the man above. Even through losing hair I have noticed no growth. In fact, I believe some growth would improve the aesthetics of my skull, so here's to hoping you are right! Unfortunately I do not think the effect is significant, if there at all.
