Is it safe to bathe a newborn every day with scented baby wash?

What's actually in it

Standard baby wash contains SLS, fragrance, preservatives (parabens or alternatives), and sometimes PEG-based emulsifiers contaminated with trace 1,4-dioxane. Newborn skin barrier is still developing over the first three months. What sits on adult skin without effect soaks through newborn skin and reaches the blood.

Daily baths aren't necessary for most newborns. Pediatric guidelines typically suggest two or three baths per week until the umbilical stump heals, and a similar frequency afterward.

What the research says

A 2026 study in J Hazard Mater decoded chemicals of emerging concern in personal hygiene products and specifically flagged vulnerable populations like infants. The combined daily exposure from shampoo, wash, lotion, and wipes added up to measurable biomarker levels in babies. Cumulative effects were stronger in newborns than in older kids.

For newborns, plain warm water handles 90% of infant baths. Scent is unnecessary. When soap is used, a single fragrance-free, paraben-free wash (Babyganics Fragrance Free, Attitude, Shea Moisture Raw Shea Baby) applied sparingly is enough. Skip the separate shampoo, lotion, and powder for at least the first month; water-only is fine. Wipes can be replaced with cotton cloths and warm water for diaper changes, which also removes a common source of preservatives on sensitive skin.
