reading dr alviarmani's site they say they can thicken thinning areas by placing single grafts in the middle of the thinning areas. if this is the case why do you have to shave your head to get a hair transplant? i want to get one but i want to do it without anyone knowing and i dont think i can conceal a shaved head for 6 months or however long it takes to regrow the hair. explain to me why you need to shave your head?
