The look and feel of synthetic hair are almost identical to natural hair. Synthetic hair will hold its style regardless of climate. Whether its hot and humid or sunny and bright, your hair will still look amazing. The only set back is you can’t apply heat like you would to natural hair (unless it is specifically labeled HD). Synthetic hair has really come a long way over the years. They now have a new and improved fiber that you are able to use a curling iron or flat iron. It is called HD fiber which means it has heat defying fiber.
