I have searched all the forums and was not sure if I should bring it to me, I've done it uuunnnd ....... the application is a bit hair-raising, because it is very thick and oily .... but you can hammer out ... a couple would be better, because we could then divide up the hair ....... so far so good :-) Anyway, I'm thrilled with the copper. The color lights and the hair looks well cared for ..... the color lasts longer than the barber with me .......
