Question
Hi, it's me again, I heard that our scalp hair are strong and very elastic that each hair can cope with strain of 100 gram???(Is it real???)

1. Can us remove the entire scalp hair by pulling it?
2. Can we remove the entire scalp hair by using strain of 500 pound or 1 ton?

Answer
Hi Bobo
Where are you getting all this information about hair?
Coping with a strain of 100 grams?  100 grams is equal to .22 pounds or 3 ounces. Hair is not really strong.  Pull a hair out of your head and see how easy it is to break it.
 1.You could not remove your scalp by pulling on the hair because the hair just pulls out.
 2. same answer.
   It is true that if you get a real hand full of hair that is difficult to pull out.  I have seen photos of someone lifting heavy weights  with the hair but is because of the distribution of many hairs
