Calculating grafts for a specific area

[RCWest]

Correct me if I'm wrong on this. If a non balding person has 600 follicular units per square inch, and wanted to achieve a 50% density in the recipient area, then 300 fu per sq. in. would be done, correct? OK, if there is a 2 inch by 4 inch area needing filling, that is 8 sq. in. So the 300 grafts (assuming they are all 2 hairs on average) multiplied by the 8 square inches would be 2400 grafts. Is this all right?? I don't see much on the topic of actual calculating, just estimates.

600 and 300 fu OMG.....i thought it 90-120 /sq inch and 40-45/sq inch would be considered as a dense pack.

Hey guys,

 

I suggest experimenting with the hair loss learning center's graft calculator. It's a very unique and interesting way to estimate density.

You're thinking square centimeters, in which case you'd be correct.

That would seem right...but that would also assume that there are zero native hairs.

thanks future ht doc! The graft calculator was really cool and helpful!

No problem Tom! I enjoy playing around with it as well! A very useful tool indeed.

[RCWest]

It is a very nice tool! But I've noticed sometimes if you input the same info and redo it several times you'll get different estimates. I did 45% density and all the areas for the heck of it, and one time I got 8000 grafts, another time I got 7600+ grafts, and once I even got 7200+ grafts. It also doesn't take into account true total surface area to cover.

Be wary of cookie cutter answers. There are lots of variables. Hair skin color match, thickness of donor hair, waviness of hair, future loss potential, and aesthetic desire.

 

You can get a guestimate with the calculator or online pic/consultations; but estimates can be off when compared to an actual in person consultation.

 

Just Monday I saw 2 fellows who had been shopping at multiple clinics in our area all day. They had estimates ranging from 800 grafts at one extreme to another clinic who said they'd do 6000 grafts and "fix the entire head" in one setting. At some point these fellows are going to have to make a decision and that is quite a range to choose from. I can't stress enough the importance of meeting the doctor at the initial consultation.
