About the italian study posted by Stevie.Dee:
http://www.tissuereconstruction.it/i...icoli&Itemid=2

From 100 donor hairs, they split them into 100+100 halves and they finally render 70+70 hairs.
So, from 100 donor hairs they get 140 hairs.
This is a 40% increase in haircounts (very nice).

BUT: they also say that the final hairs are "slightly" thinner than the originals: the caliper is 75% of the original.
Well, sorry but this is not slightly thinner. This is *significantly* thinner.
Diameter is 75% of the original, but cross section is 56% of the original (0.75x0.75= 0.56).
So, the final hairs have aprox. *half* cross section compared to the originals!! This means, half mass of hair, and probably half mass of stem cells.

So, you start with 100 full-sized donor hairs and end up with 140 hairs that are only 56% cross-section of the originals. These are equivalent to 78.4 full-sized hairs!!
So, you start with 100 full-size hairs and you end up with only 78.4 full-size hairs.

In other words, this is not hair multiplication, and this study is FLAWED.

Unless I am wrong in my analysis.... please, tell me if I am wrong...

Also, note that they don't post results beyond the 12-month timepoint. This is not enough to verify if the hairs can cycle well.
