Well, as the converstion usually goes, hair can be an indication of "wildness", in that wild leaves can have and generally do have more hair. Some say hat Plantation leaves have less hair. And then you have to throw in the idea that Broad leaves generally have more hair than smaller leaves which come from bushes. Also, some cheaper pu is made up or a mixture of 'green tea' and not actually tea tree broad leaf material which can account for some of the lack of hair. Here is the kicker, none of the above mentioned should ever be taken as a sign of determining whether a pu is made of wild tea tree as it is very difficult to tell by simply looking at it.
