Some hairs do stand up from fear. An example is the 'hackles' that stand the hair erect on the back of dogs and other animals when they are ready to fight. When the skin tightens during an adrenalin rush, the hair appears to stand up at the roots, but this is hardly noticeable with the soft hair of most humans.
it means he is kind of nervous just like the hair on our arms stand up when we are freaking out!! my dogs do the same thing when they growl at someone or some dog thats new to them!
They get their hair to stand up by the cunning application of hair gel.
You cover your hair in hair gel then you comb it up
shadow --------- Your hair --------- Your feet
The hairs on the neck and back that stand up when a dog is showing aggression are called "hackles."
When you rub a balloon against your hair, it creates static electricity. This transfer of electrons from the balloon to your hair causes the individual strands of your hair to become positively charged and repel each other, making them stand up.
If you have goosebumps
Hair on your arms can stand up when you experience emotions like fear or excitement due to a survival instinct called piloerection. Tiny muscles at the base of each hair follicle contract, causing the hair to stand up and create insulation or make you appear larger to potential threats.
Humidity and Static Electricity
The hair experiences static friction.
