24 – In Hair transplant we can replace every lost hair with new hair.
All hair loss patients desire to replace maximum or all of the lost hair with new hair. There is a simple calculation to understand. We are born with approximately 120,000 hair follicles on the scalp. About 60,000 of these are on the top of the head and 60,000 on the sides and the back of the head. By the time you reach grade IV of baldness you have lost 40,000 of these follicles from the top. We cannot remove 40,000 from the sides and the back and replace all the lost hair on the top. We will end up creating baldness on the sides and the back. We can borrow 10 – 15% of available follicles without causing apparent deficiency on the sides and the back. So, 5000 – 7500 grafts can be done in all within 1, 2 or 3 sittings. These are all that can replace the 40,000 lost hair follicles. So we are replacing less than 10% of the loss. Hair transplant is never done for replacing all the lost hair. Hair transplant aims at creating an illusion of fullness over the bald area to take away the sudden bald look. New hair follicles containing 1, 2, or 3 hair each are placed in alternate staggering or brick wall pattern to allow partial overlap and achieve more coverage of the bald area.
