Figure on about 1/2 inch a month, regardless of age, once past puberty.
Generally, he grows slowly. Technically it depends on your genes. Most people it take a year to grow full facial features and others a month or two.
no
As far as i know, hair growth speed is different for every person. some 13 years old can't even grow facial hair while others have long beards.
grow some facial hair
Generally, no unless he has hit puberty. It is the hormones that allow boys/men to have facial hair.
Normally, an 11 year old boy is not supposed to have facial hair quite yet. If you do, I would just use mens' facial hair products.
That's a disgusting concept. Christ, can you even grow a beard? This is the type of question a fifteen year old with a pedostach would ask. Wait till your nuts drop, then grow facial hair.
may
Its because you shave in one specific area and that area tends to grow faster
No, The Minoxidil chemical in Regain kills off chemicals that prevent the hair follicles from producing hair. (Thus, Regaine promotes hair growth due to the chemicals killed off instead of killing your hair) However, This chemical that prevents hair growth does not effect other areas of the body such as the armpit, pubic and facial hair regions. (This is why bald people still grow beards and other facial/body hair) Hope it answers your question.
It all depends on your genetics. Guys get facial hair and start shaving at different ages. I am 18 and have had to shave daily for over a year now and it is just annoying. I personally think that you shouldn't worry and be happy you don't have very much facial hair.
It is natural for hair to grow :)
