Answer 2

Hair traps a lot of year which is a bad conductor of heat.

• Everything that is present on our body is very adaptive in nature from a nail to a hair. Everything that is present on our body has some meaning to it. For example the hair on our head is purposely present as we have one of the most important parts of our body that runs the whole system, our brain, in that part so hair is present to save the head as much as possible.
• The presence of hair is not just a mere coincidence it not only saves the head from small shocks but the hair follicle traps air between them so that the heat that strikes the head directly would not reach the scalp and has to pass through the layers of hair present over the head.
• Since the hairs have air trapped within them it acts as an insulation  for the heat from entering the scalp and keeping the head cool. The Sweat that would be produced from the head will stay in the hair and the air will drive the Sweat and again make the head cooler.
