i've bought myself 2 Back2Natural medium brown kits.
But i've read on the instructions to avoid eyebrowns and clothing, witch means it's risky to coloring natural materials.
But what about the lace and bleaching knots?
Seems logical that this also will change color, since it is also a natural product, right?.

Therefore, Is it appropriate to use color block on the bottom of the lace, before apply the conditioner, or can it be apply without color damage the lace and knots?
I have a french lace with ofcorse bleaching knots.
How did you guys use it?

Thx,

Chris
