Do Scrubs Shrink in the Wash? Fabric Guide & Washing Tips (2025)
Whether you’re a nurse, dental assistant, or vet tech, your scrubs need to stay true to size. But do scrubs shrink in the wash? Yes, many scrubs shrink after the first wash, particularly if they’re made of natural fibers like cotton. With time, scrubs may fade and change color which is essential factor you should consider before buying medical scrubs.
This 2025 guide share washing instructions, fabric types, and expert advice to help you keep your workwear fitting just right.
What’s the main reason scrubs shrink in the wash?
Shrinkage in scrubs happens due to heat and moisture.
- Cotton fibers contract when exposed to hot water or dryer heat.
- Agitation during the wash cycle can cause micro-fiber loosening.
- Synthetic blends like polyester resist shrinkage better.
Average shrinkage by fabric:
| Fabric Type | Shrink Risk | Avg. Shrink % | Notes |
|---|---|---|---|
| 100% Cotton | High | 3–5% | Comfortable but unstable |
| Cotton-Poly Blend | Medium | 1–2% | Durable and breathable |
| Polyester-Spandex | Low | <1% | Flexible and shrink-resistant |
What’s the best way to wash scrubs without shrinking?
Follow these expert-approved washing instructions:
- Use cold water (30°C or lower).
- Select a gentle cycle.
- Avoid high heat in dryers.
- Air dry or tumble dry on low.
- Check the care label every time.
Do pre-shrunk scrubs still shrink?
Yes, pre-shrunk scrubs are treated to resist first-wash shrinkage, but not immune:
- Still shrink 1–2% with high heat.
- Best washed cold and air-dried.
- Check label: “pre-shrunk” ≠ “never shrinks.
Tip: If buying 100% cotton, consider sizing up.
Can scrubs shrink over time; not just the first wash?
Yes. Progressive shrinkage happens with repeated heat exposure.
- First wash = up to 80% of total shrinkage.
- Long-term = gradual loss of shape, especially with high dryer settings.
Prevent long-term shrinkage by:
- Washing cold.
- Drying on low or air drying.
- Avoiding fabric softeners that break down fibers.
Who should avoid cotton scrubs?
Cotton scrubs shrink the most. Avoid them if:
- You rely on consistent sizing (e.g., tailored or fitted styles).
- You use high-heat laundry machines.
- You don’t want to line dry every load.
How do you unshrink scrubs?
You can partially unshrink scrubs with this method:
- Soak in lukewarm water + fabric relaxer (or baby shampoo).
- Gently stretch by hand.
- Lay flat to air dry while reshaped.
Works best on cotton. Not effective on synthetic blends.
