TL;DR: The best laundry detergent for eczema is the cheap fragrance-free, dye-free one – not a premium “sensitive” bottle. Detergent residue sits against your skin more hours of the day than any cream you own — on every shirt, sheet, and towel — which makes laundry one of the most overlooked eczema triggers. The fix is cheap, not premium: use a detergent that’s fragrance-free and dye-free, skip scented fabric softener and dryer sheets, and rinse well. Both the National Eczema Association and the American Academy of Dermatology recommend exactly this [NEA; AAD]. Most people’s skin is fine with ordinary detergent — this is for the person whose flare has no obvious source.
Think about how much of your day your skin spends touching laundry. Your shirt, all day. Your pillowcase and sheets, all night. Towels, underwear, the collar against your neck. Whatever is left in that fabric after the wash is in contact with your skin more hours of the day than any cream you own. Call it the 24/7 contact — and it’s why laundry is one of the most overlooked eczema triggers, and one of the easiest to fix.
Up front, the reassuring part: most people’s skin is perfectly happy with ordinary detergent. If yours is, nothing here means you need to change a thing. This is for the person whose skin flares and can’t find the reason.
What should a laundry detergent for eczema avoid?
Quick Answer: Two things, and they’re the same two that come up across skincare generally: fragrance and dyes. Neither helps clean your clothes; both can sit in the fabric against your skin.
- Fragrance. That “fresh laundry” smell is added fragrance, and fragrance is the most common thing reactive skin reacts to [Cheng & Zug, Dermatitis 2014]. It’s built to cling to fabric so clothes smell clean for days, which means it stays against your skin for days.
- Dyes. Colourants added to the detergent itself — the blue or green liquid — that serve no cleaning purpose and can irritate sensitive skin.
This isn’t fringe advice. Both the National Eczema Association and the American Academy of Dermatology recommend that people with eczema use a detergent that is fragrance-free and dye-free, and skip scented fabric softeners and dryer sheets, which are designed specifically to deposit fragrance onto fabric [nationaleczema.org; AAD, aad.org]. Note the “and dye-free” — a detergent can be fragrance-free and still be tinted, so both matter.
Key takeaway: You’re checking for two words on the label, not buying a premium “eczema detergent.”
What does the fix actually look like?
Quick Answer: Pick a fragrance-free, dye-free detergent, drop the softener and dryer sheets, and rinse more thoroughly — because residue is the part that touches your skin. Even the right detergent can leave residue if it isn’t rinsed out.

| Step | Why it helps |
|---|---|
| Detergent fragrance-free and dye-free | Removes the two ingredients reactive skin reacts to; a detergent can be one without the other [NEA; AAD] |
| Use a little less than the cap says | Caps are generous; more soap means more residue to rinse away |
| Run an extra rinse; skip “quick wash” | Quick cycles skimp on rinsing, leaving more in the fabric |
| Liquid over powder | Powders can leave undissolved grit in cold or short washes |
| Skip softener + dryer sheets | Their whole job is to coat fabric with fragrance; a splash of white vinegar in the rinse softens without scent |
A useful reference point for what “fragrance-free, dye-free” looks like: All Free Clear was the first laundry detergent to earn the National Eczema Association’s Seal of Acceptance [nationaleczema.org]. Stock varies by market, so check the label of whatever you can actually buy rather than chasing one brand.
Key takeaway: It’s the residue, not the wash, that touches your skin — so rinse like it matters.
How do I test whether laundry is my trigger?
Quick Answer: Change one thing and let your skin answer. Switch to a fragrance-free, dye-free detergent, re-wash what touches your skin most, and give it two to three weeks.
- Switch to a fragrance-free, dye-free detergent and drop the softener and dryer sheets.
- Re-wash the things against your skin most first — bed sheets, pillowcases, the pyjamas and shirts you wear next to skin — twice, to strip out old fragranced residue.
- Give it two to three weeks. Skin is slow; a fair test isn’t a single wash.
If your skin settles, you’ve found a trigger hiding in plain sight. If it doesn’t, you’ve cheaply ruled laundry out and can look elsewhere — back to the full list of hidden triggers.
Key takeaway: One switch, re-wash what matters, wait two weeks. That’s the whole test.
Frequently asked questions
What is the best laundry detergent for eczema? There’s no single winner, but the criteria are firm: fragrance-free and dye-free, with no scented softener or dryer sheets [NEA; AAD]. A plain fragrance-free detergent usually beats a pricier “sensitive” one that still carries fragrance. Check the back of the box, since front-of-pack words like “gentle” and “baby” aren’t regulated.
Can laundry detergent cause eczema? It doesn’t cause eczema, but fragranced or dyed residue can flare reactive skin, because it stays on fabric against your skin around the clock. That’s why laundry is a common overlooked trigger. Switching to a fragrance-free, dye-free detergent removes the two most likely irritants.
Is fragrance-free detergent enough, or do I need dye-free too? Both. A detergent can be fragrance-free and still contain dye (the colour in the liquid), which can irritate sensitive skin. The eczema associations specifically recommend fragrance-free and dye-free [NEA; AAD]. Read for both words, not just one.
Does fabric softener affect eczema? It can. Fabric softeners and dryer sheets are designed to deposit fragrance and a residue coating onto fabric, which then sits against your skin — the opposite of what reactive skin wants. Skipping them is one of the simplest changes. For softness without scent, a splash of white vinegar in the rinse works.
How long before I know if changing detergent helped? Give it two to three weeks, and re-wash sheets, pillowcases, and next-to-skin clothes twice first to strip old fragranced residue. Skin responds slowly, so a single wash won’t tell you much. If there’s no change after a few weeks, laundry probably isn’t your trigger and you can look elsewhere.
Not sure what’s in the box? Scan it.
Detergent labels bury fragrance and dye among surfactants and enzymes, and the front of the box is usually louder than the back. Imbas reads the actual ingredient list for you and tells you, plainly, whether there’s anything worth a second look for eczema-prone skin — and, just as often, that it reads clean. Point it at the detergent you already own before you buy anything new. Imbas is launching soon — join the waitlist →
General information, not medical advice. Persistent or severe eczema deserves a doctor’s eye — and a dermatologist can patch-test you to confirm exactly what you react to.
