That's my brother in law, not me. I have posted countless images of my own hair and in the video I had wet hair, so that rules out Toppik.
Obviously I have no way of convincing you - nor do I have any desire to - but posts like yours are why I deleted everything. All I wanted to do is help and I really do not know how much proof or evidence I could have posted.
Anyway, all the backlash wasn't worth it so I'll not be posting again but you can see my results here. If you want to spend hours looking at them and trying to find where I've used Toppik then go for it, but you are wasting your time:
