Best hair concealers for thinning?

[BoSox]

I ordered some, with the spray attachment. If I can hide the hair loss for a bit, I might be ok.. I got an appoitment with a hair system expert to show me what options I have for the future in case hair cloning turns out to not be as effective as one hopes.. besides I'm not going to wait more than 4 yrs for something, I want hair, real or fake. I have been saving up money, have my own savings for hair cloning... I just hope the balance isn't 5 billion when it does come out :P
