It only takes seconds to estimate roughly how many grafts we need for a hair transplant. I forgot who emailed or posted this first but the idea is that in general we need about “1000 grafts times the norwood scale”, so if someone is a norwood 3, then in general he will need about 1000 grafts x 3 = 3000 grafts to cover the area. I have been applying this formula to most pics I have seen online and it is surprisingly accurate.

Dear Ipod,

The idea is flawed and based an era when doctors could only offer much less grafts then they can today.

I have stated earlier, and I repeat, graft estimates need to be based on the patient’s requirements. Not on the clinic’s capabilty.

In the thumb rule you talk of, let’s consider a NW 3 v/s a NW 6.

Assuming that both of them have a similar head size, same hair characteristics and a wish to go for moderate density of ?40 fu grafts/sq cm. Even not considering any other variables, the square cms of bald scalp would be too different.

A NW 6 has lot more real estate to cover (not just twice

Of the NW3).

Regards,

Dr. A

If I understand you correctly this guy should have received 1000 x Norwood 4 = 4000 grafts? But he only had 2010 grafts.

Dr. A, I know I know, it’s not accurate but I still think it is a very handy method to quickly estimate graft requirement assuming that we only need average coverage and no dense packing etc.

It will never apply to Dr. Bernstein because he has a tendency to exaggerate the norwood class of his patients. Just take a look at the pics he posted here, you have to discount the norwood class 1 level down, if he said it was a norwood 4, then it is probably a norwood 3 in reality.

Dear Ipod,

This is a NW4 caucasian patient result (4200 grafts).

http://www.hairsite.com/hair-loss/board_entry-id-49056-page-0-order-time-category-0.html

Of course, one has to factor in other things like -

- Patient’s choice of hairline (the more conservative the hairline, the less the number of grafts).
- The doctor’s philosophy towards hair restorations.
- The donor availability.

Why I posted was because sometimes such simplistic formulas can mislead prospective patients who may not have done a thorough research.

Consider these 2 NW6 patients. They each have different hair and scalp characteristics. They also have a big difference in terms of the sq cms of the recipient area.
