what is the average density of a donor (fu per square centimeter)

[mr_peanutbutter]

what would be considered an average donor density wise, what above average, what a poor donor?

[Melvin- Admin]

It varies widely, as a general rule of thumb. Visible hair loss isn't visible until around 40 fu per cm2. Donors can range from 65-80 fu per cm2.

Depends on the person, there are men who naturally born with a thin hair, like 80-90 hairs per cm2

hairs or follicle units?

It’s supposed to be in terms of FUs.

so youre saying average donor has 80-90 fu per sqcm?

Follicle unit just contains x number of hairs, what matters is hair count.

A good donor is above 100 hairs per cm2

IMHO 80-90 is above average.

I would consider that a superior donor density level.

I would say less than 60 fu/cm^2 is poor, between 60-80 fu/cm^2 is average, and more than 80 fu/cm^2 is above average.

I saw Dr Bruno Ferreira and was told I have a great donor area with about 100 fu/cm^2, I also have a lot of doubles, triples and quadruples so this would easily translate to more than 200 hairs/cm^2. 

So, if you want some photos on what an "above average" donor area looks like you can take a look at my consultation report and photos of my donor area on my thread - link below:

well, damn

 

kinda jealous

 

 

my donor density came back with 65-75 density (fu / sqcm) but i didnt get told how much hair. feels like im a bit cooked even though its hopefully within the means of average

Everyone is different! I may be fortunate with a good donor, but I am a NW5 diffuse so I will need quite a lot of grafts for full coverage.

65-75 is very decent in terms of density, most people have a graft to hair ratio of 2.05-2.25 so assuming you're in that range you're looking at 140 to 160 hairs per cm^2. 

Remember other characteristics are equally as important to help with the illusion of density, such as as hair color, scalp/skin color, and of course hair thickness. Someone with thick hair but a bad skin/hair contrast will need more grafts vs someone with a white or pale skin and light blonde hair.

Interesting discussion 

So what by rule of thumb is the no go level for surgeons ? I assume age also plays a factor in that too?
 

For example if someone has say a density in the donor of a lowish figure like 50-60 in their 30s that’s massively different to that of someone in their 50s when planning a surgery.

Would be interesting to see how many grafts you need or donor capacity you have using scalp scan or Dr. Zarev’s software. 100 fu’s per cm2 is very rare.

I would love for an opportunity for a consult with Dr. Zarev! But I cannot afford his off-schedule pricing so that's not an option unfortunately.

I tried using ScalpScan but I am having troubles making it work, it keeps saying "Not Enough Light" so I just gave up on getting it to work! I think it needs to be in a well-lit room with a proper lighting setup.

EDIT: Yes I am aware 90+ is rare, and I was very surprised myself. Dr Ferreira did say I have some miniaturisation in my donor but despite the miniaturisation he said it's easily 100 fu's per cm^2.

In all honesty my whole life I've always been told by people that my side and back hair is very dense, so it's good to know the numbers back that up. I know I have enough donor capacity to provide full coverage, but I hope it can be done in a way to minimise FUE scarring as I like to have my hair as a short fade.

Average density is not only measured by number of grafts per sq cm, it's also depending on the type of hair and scalp empty areas measurements, 50-60 sq cm of my type of hair won't give the same coverage effect of a candidate with fine thin blonde hair or candidate with thick curly hair, there's no binary formula, every candidate is a unique case with it's own potential, average density is just a single property for evaluation.
