I have very thin hair and have fussed with wigs and with KeriFiber. I am able to get adequate coverage with KeriFiber and may travel to a five-star rating but need to use it a bit more to be sure. It is in most ways much easier than a wig except I get multiple days out of a wig and only a day with the KeriFiber before I need to redo my hair -- that is not the fault of the KeriFiber but my terrible hair.
