My head is abnormally small, is there anything I can do to ever so slightly widen it? (Photo)

Hi, my head circumference is 55 cm and I am 183 cm tall. Currently, my head looks extremely disproportionate and I would like to change my appearance so that I can better fulfill my job as a barrister. (Looks matter in court) I don't need it to be too much wider, just 1-2 cm wider would satisfy me. Is there any procedure that can help? Is there anything I can do? My bathroom is being renovated atm, the second image is altered to what I wish my head was. I am sorry for the mess. Would HGH work?
