Is Hair dye / perm solution toxic to dogs & cats?
Also known as: hair dye / hydrogen peroxide / perm solution
🚑 What to do right after ingestion
Flush contacted skin with water immediately, do NOT induce vomiting; the vet assesses corrosive injury. Never dye a pet with human products.
Toxicity notes
Contains peroxide, ammonia and pigments: licking causes corrosive GI injury, skin application absorbs (people «dyeing» pets is the risk), and dark dyes may carry lead.
Poisoning symptoms
- • Vomiting
- • Drooling
- • Mouth ulcers
- • Lethargy
- • (Skin absorption) tremors
Symptoms can be delayed (e.g. onion/garlic-induced hemolysis may take days) — a pet looking fine right now is no reason to relax.
FAQ
How much causes poisoning?
Contains peroxide, ammonia and pigments: licking causes corrosive GI injury, skin application absorbs (people «dyeing» pets is the risk), and dark dyes may carry lead.
Can I make my pet vomit at home?
Home-induced vomiting is not advised: corrosive cleaners, sharp bones or existing neurological signs make it dangerous, and improper technique risks aspiration pneumonia. Vomiting should be induced by a vet with proper drugs at the right moment — most effective within 1-2 hours. So “head to the clinic as soon as you know” beats “try to induce vomiting first”.
