Can I dye my hair while nursing?

Jayjay

I was going in to the salon today to dye my hair. the stylist told me that she has to discolorate and then do an overtone. I know nothing about it. She uses a product from L’Oréal that apparently has les ammonium and doesn’t enter breast milk but she told me to consult with my dr. Does anyone know if it’s safe? Or should I wait? I really need to do something about my personal image 😪
