<font color="purple">I bought some Kanekalon hair for my braids. If it says 100% Kanekalon on the package, then it's what I need. Kanekalon is synthetic hair, and not a mixture of both synthetic and human hair. It is not required to use heat on this type of hair. Like plastic, it can melt and have an awful odor. Only human hair can use heat, but very carefully. And to finalize your question, if you have the money, you may try to find 100% human hair in beauty supply stores, wig catalogs, or finding some online. I hope I answered your questions. Good luck in your search. </font>
