Is this safe for 0-6 month old newborns to use Hydrolyzed Keratin?

YES - Generally Safe
Danger Score: 2 (Lower is safer)
Quick Answer: Hydrolyzed Keratin is generally considered safe for 0-6 month old babies when used in topical products. Always consult your pediatrician for newborns.

ℹ️General Overview

For newborns and babies (0–6 months), hydrolyzed keratin is generally considered low risk when used in small amounts on hair or skin. Official reviews say it is unlikely to cause serious harm, but we don’t have many studies specifically in very young infants, so extra care is wise.

What to Do

If you choose to use a product that contains hydrolyzed keratin on your baby: pick products made for infants when possible, use only a small amount, avoid applying to broken or sore skin, and do a simple patch test first (apply a tiny amount to the forearm or thigh and wait 24–48 hours). Stop use and talk with your pediatrician if you see redness, rash, or swelling. If your baby has eczema or known animal-protein allergies, check with your pediatrician before use.

⚠️Warnings

Assessments by Environment Canada find it not expected to be systemically toxic, and the Cosmetic Ingredient Review notes industry recommendations for safe use. Still, because hydrolyzed keratin is an animal-derived protein there is a small risk of skin allergy or sensitivity. Some product-certification programs restrict its use unless manufacturers provide safety data. Avoid application to broken skin and watch for any signs of irritation (redness, rash, itching, swelling). If your baby develops hives, difficulty breathing, or facial swelling, seek emergency care.
