Sugar Beer Bottles

I bottled my beer four days ago and still has no head, but it's the carbonation, no one knows why?
it was a lot of 6 liters and 4 oz bottles with thoughts of corn sugar.Any why there is no head in this?
You did not see any head until you open the bottle and pour into a cup. Besides, four days is too soon to expect to see much air and your head. If a bottled beer, waiting a few weeks at room temperature around before it is ready. If a bottled beer, it is necessary to wait several months at lower than room temperature before it is ready.
