yes marco, Cole did a density study with two different orientations and four different densities of hair a while back and found that body hair grew best at about 30 hairs per square cm with saggital slits. Much more hair grew period, not merely yield, over much higher denstities.
Ask Cole about it when you get the chance. Over the long haul (3 years or so, some more of the dense packed BHT’s might grow in of course)
I have a little theory about this and that is a bunch of body hair densely packed anywhere might have a hard time growing because its actually very densely packed on our bodies, but only about a fifth of it is growing on the arms and legs and a third to a forth on the chest. If it all grew at once, hairy men like me, would look like apes. There might be a signalling mechanism between them that disallows other body hairs to be in aganen in close proximity.
OR All that might be wrong and over several years all of it will grow. Mixing body hair and head hair might be the best route to get the most growth over all. Mwamba has stated that he has seen cases where the head hair amongst body hair seems to help the body hair grow. The signalling envrionment between the follicular units is probably profoundly complicated in totality, but they are learning.
