Here is the text from the readme on that hair:

You may create commercial or non-commercial render with this product. You are allowed to modify the hair like changing the dynamic or styling settings for your own purposes.

You may NOT sell the product in completely, partially or modified or claim it as your own.

It seems to allow redistribution as long as it is not sold...?
