"Sikh men commonly wear a peaked turban that serves partly to cover their long hair, which is never cut out of respect for God's creation. Devout Sikhs also do not cut their beards, so many Sikh men comb out their facial hair and then twist and tuck it up into their turbans along with the hair from their heads. Sikhism originated in northern India and Pakistan in the 15th century and is one of the youngest of the world's monotheistic religions.Hindu men wont wear turbans..Wearing a turban is one of five symbols that define Sikhs.
Kesh - uncut hair covered by a turban"

From http://www.sikhmarg.com/english/The-Sikhs.html

"The Hindus cut their hair but all the Guru Sahib had unshorn hair. Keeping unshorn hair is one of the major obligations for a Sikh. In Sikh faith even God is believed to be one with long unshorn hair. (Guru Granth Sahib p. 567)"
"Guru Sahib told the Sikhs to remain distinct. A Sikh must not have social or personal relations with the one who has shaved his head after having once adopted the Sikh faith. A Sikh must not marry a non-Sikh. Practice of female infanticide is strictly forbidden in Sikhism. Getting a daughter married to a clean-shaven (Hindu or any other person) is a sin for a Sikh. Such a person does not remain a member of the Sikh brotherhood. Cutting hair from any part of his/her body makes a Sikh a Patit (an apostate)."

Answer 2

Their hair is too hard and their scissors are too blunt.
