Few things feel nicer than slipping into freshly washed pyjamas. But last week, I did exactly that and my back erupted in hives within minutes.
My hunt for the culprit led me to the laundry detergent box, where the ingredient list read like a chemistry exam I hadn't studied for:
- 15-30% Oxygen based bleaching agents
- 5-15% Non-ionic surfactants
- >5% Zeolite, Cationic surfactants, Poly carboxylates, Phosphonates, Soap
- Also contains Optical brightener, Perfume
These might as well be hieroglyphics for all the sense they make to someone trying to avoid skin irritants.
When environmental triggers can cause serious skin flare-ups (as my angry, itchy back was proving), those of us with reactive skin need to know what we're actually putting on our clothes.
After some research and testing, here's what actually works for washing clothes without the skin drama:
- Go liquid, not powder. Powders leave more residue in fabric fibres, which means more irritant sitting against your skin all day.
- Choose non-biological. Bio detergents contain enzymes that break down protein stains brilliantly, but damaged skin barriers don't appreciate the extra activity. Many people see immediate improvement after switching.
- Halve the recommended dose. Detergent companies want you to use more. Your skin wants you to use less. Start with half and see if your clothes still come out clean (they will).
- Be strategic about what gets the full treatment. That muddy dog towel? Fine, use the full dose. Your pillowcase that sits against your face for eight hours? Minimal detergent, maximum rinse.
- Skip the fragrance entirely. Artificial fragrances are one of the most common skin irritants. If you're reacting to your washing, fragrance is often the culprit.
- Add an extra rinse cycle. Yes, it uses more water. Yes, your skin will thank you. Think of it as insurance against residue.
- Don't overload the machine. Cramming in "just one more towel" means nothing rinses properly. Give your clothes room to actually get clean.
The irony isn't lost on me: we scrutinise every ingredient in our skincare (and rightly so) but happily wash our bedsheets in ingredients we can't pronounce.
For those dealing with unexplained reactions or flare-ups, your laundry routine might be worth investigating. Sometimes the simplest changes make the biggest difference.
