Biofiber cannot be compared to natural hair because biofiber is an artificial, synthetic hair that does not grow. Biofiber limits your life. Because the fiber is synthetic, you need to avoid swimming in the pools with color, or having your hair straightened. You also need to avoid being in hot environments. If your donor site is not suitable for harvesting, then you might think about having a biofiber transplant as an option. However, you may not find it comfortable carrying on daily life after biofiber transplant.
