Hi, I'm a complete newbie to all this and I'm very interested in finding a way to color my stange hair! It's grey on top at the crown and front hairline to my ears but reddish-brown below my ears around to the nape of my neck...strange...I'm wearing my hair longer now and the first time I wore it up, friends were shocked at how dark the bottom of my head was (the top grey had hidden it)! Anyone else have this type of stange hair coloration?
