Empowering mothers worldwide through connection, support, and shared experiences ✨
Community opinion is mixed: many moms say hair colour (especially ammonia-free, no bleach) is fine in a well-ventilated space, while some pediatricians advise against it; keratin is more often considered risky. Avoid retinol in skincare while breastfeeding.
⚠️ Caution:Opinions differ and some pediatricians advise against chemical hair treatments while breastfeeding. Check with your own pediatrician before coloring or doing keratin, and always avoid retinol in skincare while nursing.
Moms worry that chemicals from hair colour, keratin, or skincare could pass into their breast milk and harm the baby, while also wanting to feel like themselves again. The community offers reassurance that ammonia-free, no-bleach colour done in a ventilated space is widely considered safe, that skin absorbs little, and that the main ingredient to genuinely avoid is retinol - while honestly noting that some pediatricians still say no, so a quick check with your own doctor settles it.
Here's what moms in our community shared based on their own experience.
Hair colour is considered safe as long as it doesn't include bleaching.
The skin doesn't really absorb chemicals from hair colour, so it shouldn't affect breast milk. Get it done in a well-ventilated area and wash hair thoroughly afterward. It's also considered safe in pregnancy, though hormonal changes can make the colour turn out differently.
Some pediatricians advise against hair colour while breastfeeding, so check with yours.
For skincare, one mom avoids only retinol (which has studies showing harm to children) but uses all makeup including foundation, blush, and lipstick through pregnancy and postpartum.
For hyperpigmentation, a doctor confirmed glycolic acid toner was safe to use postpartum, though it faded on its own anyway.
Keratin treatment is felt by some moms to be unsafe while breastfeeding, similar to the caution around hair colour.
