0-6 month old newborns • Skin contact product
For newborns and infants (0–6 months), keratin is best treated with caution. The chemical itself has low signals for cancer or developmental harm, but some governments and industry groups limit or recommend how it is used. Babies’ skin is very delicate, so it’s safer to avoid products with keratin unless a doctor advises otherwise.
If you are considering a product that lists keratin: 1) Prefer products specially made and tested for babies/newborns. 2) Don’t use on broken or inflamed skin. 3) Do a tiny patch test on a small area of the baby’s thigh and wait 48 hours to watch for redness or rash. 4) If your baby has sensitive skin or eczema, avoid keratin entirely unless directed by a pediatrician. 5) When in doubt, ask your child’s healthcare provider before using a product with keratin.
Main source of caution comes from government or industry restrictions (for example, Health Canada lists use restrictions and the Cosmetic Ingredient Review gives usage guidance). Watch for skin redness, swelling, dry patches, or increased fussiness after use. Avoid using keratin-containing products on infants under 6 months unless recommended by a pediatrician, and do not apply to the face, mouth area, or damaged skin.
