Hello, im 18 years of age the doctors tell me im still growing and my head is small for my body will it grow more as I grow?

Not much. The majority of head growth is finished by age 9 although the bones forming the skull do not completely fuse for many years thereafter.Most males finish their linear growth by 17-18 but an xray of your wrist and hand can show how much more growth to expect.The size of your cranium does not reflect what you can do with it.A portion of the normal population will have both small or oversized heads.
