When does dense packing become overpacking (eg. graft suffer from not enough space)?

[Lotsofhair]

Dear all,

 

I wish (as most people I assume) for a dense, very dense hair transplant.

 

However, when does a hair transplant density reach a point where too tightly packed grafts actually hamper graft growth and survival ; a point when - paradoxically - more becomes less ? Things to take into account are, I think :

 

- blood supply

- oxygen

(please feel free to list more or elaborate)

 

Naturally, hairs grow at a rate of anything between 80 and 110 grafts per cm2 I think (correct me if I'm wrong)? So why can't hair transplants achieve the same without risking grafts from not growing?

 

So what limit do doctors agree on then? I see some clinic listing 70 (hair clinic 1) or 75 (hair clinic 2) g/cm2.

 

I've read an interesting post where a coalition doctor explained that he would watch for too much bleeding during graft implementation as this is a sign for project or potential necrosis and thus decrease the planned density as he would go on. I did not understand the medical reasoning behind this. Would also be interesting to know on a side note.

 

Thanks!

 

ps : also I'm confused whether people mean 80-100 GRAFTS per cm2 or 80 HAIRS per cm2 when talking about natural density.

[Cant decide]

80-100 refers to grafts per sq cm. I think most clinics agree that anything over 70 per sq cm in one procedure is a bad idea. Some would even say 65.
