Hair dying while breastfeeding?

I don’t see the problem but my mom says that the chemicals will run through my system to my breast milk. But I keep getting mixed reactions about this…so is it safe or not??

Hair Care Products (dyes, permanents, relaxers)

There is no evidence that hair care products (dyes, permanents, or hair relaxers) used by a nursing mom have any effect on her breastfeed

According to theBREASTFEEDING ANSWER BOOK, published by La Leche League International, no evidence exists that the nursing mother’s use of hair-care products, such as hair dyes and permanents, has any effect on her breastfeeding baby. When a mother uses hair-care products, some of the chemicals will be absorbed through her skin. If her scalp is healthy and intact, less will be absorbed than if the skin on her scalp is scratched or abraded.
