Jaycee,
Bleaching is a recurring topic on the forum. You have black hair and that is the 'trickiest' to bleach. The darker the hair the longer it takes to bleach. So moving to a lighter color on the front requires less bleaching. All knots are bleached. It may not be as undetectable as lighter hair but the factory is walking a fine line with black hair. If they were not bleached they would be much more noticeable. They factory can move the needle a little bit to 'well bleached' which we do on your orders.
Regards,
John
