What the sources say
MotherToBaby lists ammonia as a common ingredient in hair dyes and perms, notes that a strong odor does not mean high exposure, and says treatments used as directed are not expected to greatly increase birth defect risk. NHS advises dyeing in a well-ventilated room. Limit: follow directions, ventilate, wear gloves; ammonia-free dyes are an option. Breastfeeding: little is expected to reach milk.
