The problem I saw is that they title the item as "Cosmetology Mannequin Head 100% Human Hair Hairdresser Training Super Long 26-28" but when you go down to the item description, they write :

★ Unique Material: 100% High-temperature fiber hair, Real human hair-like texture, Suitable for Curling, Cutting, Braiding, Setting and Updos; When applying with heat, please use the curl iron under 150-170 Celsius about 15 seconds.
