Which product is best to give the illusion of a full head of hair?

I just ordered a bottle of Hair So Real from Amazon for $17.98 (tax included) for 28 grams.
I bought this because I've read some articles and seen a video on how it compares favorably with Toppik for much cheaper.
From what I read, it seems like all these products are similar, and it just comes down to price. I'm guessing Hair So Real is a good example of what to expect. I'm eagerly waiting for it arrive (I wish they sold this in stores) so that I can make my decision of whether or not I will get a transplant. It all comes down to how effective it is; how easy and quick it is to apply; and how cheap it will be in the very long run.
