Is 200 grafts per square centimeter reasonable and safe?

It is not reasonable nor safe.  Normally human hair has a density of 70-90 follicular units per square centimeter, where a graft is essentially the same as a follicular unit.  Not only is 200 not reasonable, but if grafted in this density can cause necrosis of the scalp.  If a clinic is suggesting grafting in this density, they are not aware of basic scalp anatomy and are just trying to sell you a procedure.  Run!

In general, an average person can have about 200 hairs in a square centimeter.

In general, an average person can have about 200 hairs in a square centimeter.

In general, an average graft may have one, two, or three hairs.

If you are trying to put 200 single hairs grafts in a square centimeter, that would mean you are trying to replicate an average density.

However this is not reasonable in a normal hair transplant surgery.

200 grafts per square centimeter

No:  200 grafts per square centimeter is more hair per square centimeter then natural occurring hair.  Secondly, there is no reason why someone would want to transplant in a patient who most likely needs those grafts in other places.  Lastly, I would suspect that if someone tried to do that, most of the grafts would fail to grow.

Thank you for posting your question. A density of 200 grafts per cm2 is too much. Normal density pending on the patient's background and ethnicity can be anywhere from 70 up to 100 per cm2. Anything more is not safe, or natural. I wonder if you are asking 200 hairs per cm2? If that is the true question, then it is possible pending on the density you have in each graft, which can give you the final hair count. a single graft can have 1 hair and we have seen in our clinic as much as 8 hairs in a single graft. Hope this helps.

Recipient area density

A density of 200 grafts/cm2 in the recipient area is not a reasonable density and possibly far more density than you need
