BLEACHING KNOTS: WE DO NOT RECOMMEND BLEACHING THE KNOTS! If the lace is not a desirable color then you should use a cap that is more flesh toned underneath. The developer/bleach can eat at the lace. It also loosens the knots causing more shedding, and breakage. This has been a common problem that can bald the lace quicker do too over shedding. However if you would like your knots bleached please let a professional bleach your knots or someone skilled.
