Minimum Number of Grafts Needed For a Hair Transplant To Make a Difference

What is the minimum number of grafts needed for a hair transplant to make a good cosmetic difference? I think I am a Norwood III, would 1800 hair transplant grafts be enough?

The minimum number of grafts necessary to make a significant difference will obviously vary from patient to patient. There are 3 primary factors to consider. First is the caliber (diameter, thickness) of each individual hair shaft in your donor area. It goes without saying that the greater the caliber of an individual’s hair, the greater the resultant density will appear after the transplant grows in. However, it frequently surprises people how much of a difference this can make. If you compare the diameter of an individual hair in someone who has very fine flyaway type hair to someone with coarse hair, you can quickly understand why the person with the coarse hair might have a results that look 4 times or more denser. The second consideration has to do with the amount of curl of the hair. When curly hair grows in after a transplant, it has the tendency to look much denser than straight hair. The third factor is simply that what satisfies one patient may not satisfy another. I frequently see men who have had small transplants but are ecstatic about the results. Conversely, I will see men who I think have had dramatic results but are still not happy.

In general, I would think that 1800 grafts would make a significant difference in someone with Norwood type III balding. Sometimes it’s helpful to look at this mathematically. Moving 1800 grafts is equal to moving approximately 4 to 5% of the original volume of most men’s hair. That 4 to 5% would typically be distributed over a recipient area representing approximately 15 to perhaps 20% of the scalp area wise. So you can see that if you spread 5% volume over 15 to 20% area, you would be looking at one quarter to one third density. While that obviously is not high-density, in most men that would lead to a good cosmetic result. I hope that helps.

Blaine Lehr, MD Perhaps the greatest compliment and best introduction to Blaine Lehr, M.D. is a statement from O'Tar Norwood, M.D., one of the true pioneers in the field of hair transplantation (creator of the Norwood Baldness Scale, author of 1st two textbooks of hair transplantation, cofounder of the International Society of Hair Restoration Surgery, founder of the Hair Transplant FORUM International, and recipient of two of the highest awards---Golden Follicle Award and Manfred Lucus Award). Before he retired, Dr. Norwood stated, "Over the last 30 years, I have been associated with, worked with, and in fact trained many of the other leading hair transplant surgeons in the world. As the demand for my services increased , I knew I needed an associate, and I knew because of my reputation, I could choose anyone. I did not want to sell out to one of the large nationwide franchises. You have no control over their integrity or the quality of their work. I first began working with Blaine in 1993. I recognized his natural ability immediately. Just as importantly, I found him to be honest in all circumstances. He is a hair transplant surgeon of the highest quality". Dr. Lehr now runs the Norwood and Lehr Hair Transplant Clinic in Oklahoma City where they utilize 100% microscopically dissected follicular units. Dr. Lehr is a member of the International Alliance of Hair Restoration Surgeons and recommended by the American Hair Loss Association. Visit Dr. Lehr's Website: www.norwood-lehr.com
