This is my review of the 18" Wavy machine weft that I bought from http://www.perfectlocks.com/. I REALLY like this hair because it blends very well with my natural hair when I straighten it with the flat iron. It straightens easily with the flat iron and can wave back up with only water. I highly recommend this hair for anyone who is transitioning to their natural hair or natural already, but it's great for EVERYONE!! Go Get it!
