you should probably email BA with that question.
in regards to bleached knots, I honestly think there is a misconception with this. if you have dark hair, the knots will NOT be blonde. the term "bleached knots" means that the factory has lightened the knots so that they are not little BLACK dots, but they will not be invisible or even blonde. Many companies will not even offer bleached knots on black or dark brown hair. I bring this up because someone emailed me about a piece , they said "none of the knots are bleached". so I had the customer send it to me, when I received it, ALL of the knots were bleached quite perfectly, it was just that the customer was expecting to see white or very blonde knots. this is simply not the case.
bleaching the knots on black hair or dark brown hair simply is to lighten the knots, to do so further can cause damage to the hair and then cause shedding.
many like the lighter knots and will rebleach them when they get the piece, this is fine but one does so at their own risk.........being careful not to overprocess the hair and damage it.
I just wanted to bring this up because I think there is a misconception as to what bleached knots mean.
