I'm 27 yrs old and still no facial hair. Any suggestions? (photos)

Beard hair or facial hair is a genetic trait. If you cannot grow a beard past your puberty years, there isn't much you can do to make it grow.  Surgery may be an option

thin beard can be genetic but hair transplant can be done. You can see a hair transplant specialist to find out about your options. There is many factors involved therefore make sure you chose a doctor with experience in beard hair transplant.  

It takes age (genetic
triggers occur in family lines) so you need to find out when your father or
grandfather started to grow their hair. It is unusual for a man of your age not to have facial hair but your family history might give you insight into this. Your hormones should have kicked in
nicely by now.  Beard transplants can be
done if the hair has not grown in yet
