You lose a similar amount over any given exposed area of your body and only slightly more through the head due to a higher concentration of blood vessels close to the surface and a smaller percentage of fat.
The common misconceptions are that one loses between thirty and eighty percent of body heat through ones head. The reasons behind this are two-fold.
Firstly, people seldom wear hats or head-coverings until cold conditions becomes fairly acute. However, we seldom run around without clothes in all but both the hottest weather and liberal surroundings. At most points a person will have the majority of their surface area covered with clothes. If it were bitterly cold you would be unlikely to roll up one sleeve, but this would lose a similar amount of heat.
Secondly, your head contains your brain. Your body protects your brain in the same way as any major organ. It withdraws blood from non-essential extremities to concentrate on the core of the body and, of course, your brain.
You feel the cold in these areas last but more often than not the body will have to work harder to protect the head due to clothing on the torso and limbs as well as socks, shoes and underwear. Your head feels cold in order of essentials as well, the ears nose and then lips before the core.
It is possible that you lose about thirty percent when moderately clothed through your uncovered head, but then it is also possible that your head loses less than any other area when naked due to the insulation properties of your hair.

What percent of body heat is lost through your head?
I gotta go with the NY Times on this one. It would seem that it's not entirely true. Body heat escapes through any exposed surface. The larger the surface, the more heat that escapes. If you have less hair, naturally, you'll lose more heat through your head (I happen to shave mine, so I know!) http://www.nytimes.com/2004/10/26/health/26real.html

How does your body lose heat through urination and defecation?
Heat loss through urination and defecation occurs due to the high water content in urine and feces. When urine leaves the body, it takes away some heat with it. Similarly, when feces are eliminated, they also carry away a small amount of heat. However, the overall amount of heat lost through these processes is relatively small compared to other mechanisms such as evaporative cooling through sweating.

A person can lose/gain heat in five ways:Conduction is the transfer of heat directly from one object to another. For example: sitting on the cold leather seats of an un-warmed vehicle.Convection is the loss of heat through moving air or liquid. When it is cold we lose heat through the blowing windEvaporation occurs when a liquid changes into a gas. Sweating is an example of evaporation.Radiation is heat sent outward into the air from your body and into nearby colder objects. It is also known as infrared energy.Respiration is also when our body breathes in warm and humidified air and exhales carrying heat from the body.
