I am a nurse by profession, my brother is a graduate hairstylist, we both ever discuss about this, the safest way Is you pump your milk to stock up at list 2 weeks minimum, during rebonding and up to two weeks avoid Brest feeding but continue to pum as usual to keep the milk flow, do not feed the child. Hair chemical is harmful, even some skincare too, I hope this can help you Mdm. Cheers and happy parenting
