I placed an order for a supposedly Silky Straight Human Hair Jet Black unit and ordered it from seller zero_ff. First off I was sent a unit that was in the color brown. Secondly when I was using a curling iron set on only 210, the hair burnt and wouldn’t curl properly. That tells me that this was NOT human hair. Be extra careful when ordering hair from this seller. Fortunately I requested a partial refund and it was honored. It was so bothersome to have to get the hair dyed and then to top it off it is not curling as human hair should curl. Shameful seller!! BEWARE of seller zero_ff on the DHGate website!!
