Can you tell me how i can stimuate facial hair growth?

You can't: If you're normally masculinized by your hormones, how thick your beard is reflects your genetic heritage. Thick-bearded, hairy-chested guys go bald faster than other guys -- just look around you. Justin bieber can't grow a beard but this doesn't seem to bother him. Many women prefer a less scratchy man. Embrace and enjoy whatever mother nature gave you.
