I currently have unbleachable hairline knots in my new system. I find this sometimes happens on hair systems with SFS front but thinskin or ilace base - not sure why, perhaps it's the hair used in the skins.
I've left the knots in bleach for about 50 minutes, and only a few of them got bleached. The rest stayed totally original colour. I've had this issue before with an ilace piece, and after 3 bleach attempts I gave up.
With SFS and #64 systems, I've never had this problem.
I'm currentl wearing my system with unbleached hairline knots, and it actually looks fine because it's quite a thick hairline... but I wouldn't mind getting some of the bleached, perhaps there is some way?
I may be wrong here but I don't think you can bleach knots on an i-lace piece as the knots are sandwiched between two seperate materials.....the bleach wouldn't even touch the knots.

oh, I understand. sorry, I was confused.
you should be able to just bleach the sfs area in the front without issues.
use a thin coat so it doesn't expand and travel up the hair shaft.
