Summary:
A complete protein is a protein source that "contains adequate proportions of the nine essential amino acids" that our body can not produce on its own.
Relatively low in protein, a single teaspoon of half and half contains 0.2 grams of protein, or about 0% of recommended daily values. [1]
To get the adequate amount of protein with half and half alone, you will need 319 teaspoons of half and half (1600 grams) for an average female, or 383 teaspoons of half and half for males. [4] That's over 2090 calories, and a lot of half and half! Pairing half and half with a richer protein source is a good idea.

Proportionally, half and half does contain abundant amounts of 8 out of the nine essential amino acids. However, half and half is a little short on lysine.[1]
To have adequate amounts of all nine essential amino acids with half and half alone, you will have to eat 251 teaspoons of half and half (1257 grams) for an average person. [2]
That's about 21% more half and half to compensate for the lack of lysine, compared to the protein requirement alone.
