Question
A breastfeeding mother is worried that harmful substances may be present in her milk after hair straightening and asks whether she needs to go to the hospital for a check-up, as well as the impact of hair straightening on breastfeeding.
Answer
Medically, there is no specific measurement of the effect of hair straightening agents on breast milk, so there is no need for routine blood tests. Although hair straightening during breastfeeding is not recommended, there is no need to be overly concerned. If you are very worried, the only option is to temporarily stop breastfeeding and switch to formula milk. At the same time, frequent washing of the hair can reduce the impact of residual hair products.
