General information only
Skin, scalp and hair conditions can look similar while needing different care. Do not use this site to diagnose a rash, infection, allergy, hair-loss condition or persistent acne. Product suitability depends on your medical history, medicines, pregnancy status, allergies and the exact formula.
Stop and seek help
Stop using a product and seek appropriate care for severe burning, swelling, breathing difficulty, blistering, rapidly spreading redness, fever or other signs of a serious reaction. Emergency symptoms require local emergency services, not an email to this website.
Patch testing and labels
Patch testing can reduce some surprises but cannot guarantee safety. Always read the current physical label, warnings, expiry information and manufacturer directions. Marketplace photos or older articles may not reflect a reformulation.
