Hello. i would like to ask if there is anything that can be done to increase head size? i have small hands, ears, feet and head. i am desperate.

Generally not: Most people have reached their maximum hands-feet-head-ears size by age 17-21. Without nutritional problems or chronic childhood illnesses, sizes of these body parts are largely based on genetic inheritance. Aside from eating right, exercising, sleeping well, and being happy, there's not much a person can do to increase the sizes except that weight training can make hands and feet muscles bulkier.
