An artificial hair bundle (10) which comprises a first artificial hair (1) made of a polyester resin and a second artificial hair (5) made of a polyamide resin blended together. The first artificial hair (1), which is made of polyethylene terephthalate and polybutylenne terephthalate, has a sectional diameter almost the same as natural hair and a bending rigidity almost the same as natural hair. This bending rigidity ranges from about 6.5 to about 7.8 x 10-3 gfcm2/strand at a humidity of 40%. The first artificial hair (1) regulates the converging properties of the second artificial hair (5) so that the first and second artificial hairs (1,5) behave in the same way as natural hair.

Le premier cheveu artificiel (1), constitué de téréphtalate de polyéthylène et de téréphtalate de polybutylène, présente un diamètre en section presque identique à celui d'un cheveu naturel et une rigidité en flexion presque identique à celle d'un cheveu naturel. Cette rigidité en flexion est comprise entre environ 6,5 et environ 7,8 x 10-3 gfcm2/fil à une humidité de 40 %. Le premier cheveu artificiel (1) régule les propriétés convergentes du second cheveu artificiel (5) de manière à ce que les premier et second cheveux (1, 5) se comportent de la même manière que des cheveux naturels.
