Itelogen effluvium

I-Telogen effluvium yinto yexeshana, kodwa eqhelekileyo yokulahleka kweenwele. Umnyhadala woxinzelelo ubangela ukuba iifollic zeenwele zingene kwisigaba se-telogen ngaphambi kwexesha. Oku kubangela ukuba iinwele zinciphe kwaye ziwe.

Iinwele zihlala ziwela ngaphandle kwentloko, kodwa kwiimeko ezibi kakhulu, zinokuwela kwezinye iindawo emzimbeni, kubandakanya imilenze, amashiya, kunye nendawo ye-pubic.
