It depends on the person
As long as it takes for your hair to grow back when you have a haircut.
Actually, boys' hair can grow just as long as girls' hair. How long your hair grows only depends on how short you cut it.
Normally yes, but if you happen to be dead at the time of the trimming of the hair then as long as you're dead, your hair will not grow back.
Generally girls have long hair, and boys have shorter hair.Because girls like to pretend as princesses, and boys are too lazy to take care of their hair.
it depends how bad you grow your hair back maybe a week or two
it grows back if you trim it a little once per month. Then your hair can grow faster and longer.
Of course boys can have long hair its just girls like it better long and boys prefer its short its just to make girls and boys equal.
i let it grow then comb it back and just let it grow
Guy can grow long hair, but facial hair is due to the levels testosterone men have more than women.
Probably
Around a month.
welll it should eventually grow back but it takes a LONG time ...
