How many times does it need to be said. Just look at the hd photos. Look at the hair direction of his thick side-hair in (d), see how the lines are horizontal and pointed toward his forehead? Now do the same for a, b, and c. See how they're vertical and pointed down toward his ears?
Now imagine applying some hair gel to (d), brushing the side hair down toward his ears, and then giving the top a noogie. It will look exactly the same as abc. You all know the massive difference in the appearance of volume between wet and dry hair. If you don't, your hair is still thick as f***. There is no regrowth in the photos and no sign of healthier hair other than the illusion due to it being so dry in comparison to abc.
