Ngayau is a tradition of the Dayak tribe who inhabit the island of Kalimantan, both Dayaks living in West Kalimantan and other Kalimantan. The Iban and Kenyah tribes are two of the Dayak tribes who have the Ngayau custom. .In the true tradition of Ngayau, Ngayau cannot be separated from the victims of human heads from the enemy. The most popular images of Borneo so far are those related to head hunting (Ngayau). .Carl Bock's work, The Head Hunters of Borneo, which was published in England in 1882, contributed much to the image of the Dayak as "head hunters".

The tradition of elongating ears for Dayak women in East Kalimantan is a symbol of beauty. The longer the ears of a Dayak woman, the more beautiful she is. Unfortunately, this long ear tradition is slowly disappearing. .the majority of Dayak women are now starting to leave long ears over the times. Now millennial generation Dayak women no longer use this tradition..
