Can You Put a Hoodie in the Dryer? Dos and Don‘ts

The Short Answer

Yes, you can put most hoodies in the dryer. But that does not mean you should.

The difference between a hoodie that lasts for years and one that shrinks after one wash often comes down to how you dry it. A dryer can be safe if used correctly. Nonetheless, the same machine can ruin your favorite sweatshirt if you are not careful.

This guide walks you through exactly what to do and what to avoid.

Why Dryers Cause Shrinking

To understand how to dry safely, you first need to know what happens inside a dryer.

Cotton cloth threads are stretched tight when they are woven into fabric. Think of it like pulling a rubber band. The threads are under tension. When they meet heat and moisture, they relax and snap back to a shorter, more natural length. This is called “shrinking when relaxed.”

Three things work together during a drying cycle:

Heat: High temperatures cause threads to get tighter
Tumbling: The constant movement creates rubbing between clothes
Fast drying: Water leaves quickly, locking threads in a smaller state

For cotton hoodies, this combination is especially risky. A cloth expert explains that cotton naturally soaks up water, causing threads to swell. When heated, they get smaller. That is the main reason hoodies shrink.

Which Fabrics Are Most at Risk

Not all hoodies react the same way to heat. The material matters more than anything else.

100% Cotton – Highest Risk
Pure cotton shrinks the most. You can expect a 100% cotton hoodie to get noticeably smaller when exposed to high heat. Even hoodies labeled “pre-shrunk” can still shrink. The pre-shrinking process only reduces the risk. It does not remove it.

Cotton-Polyester Blends – Medium Risk
Blends like 80% cotton and 20% polyester will shrink, but much less. Polyester is a synthetic material. It does not shrink. The more polyester in the blend, the less your hoodie will change size.

100% Polyester – Low Risk
Synthetic fabrics handle heat better. You can safely dry a polyester hoodie in a machine. However, very high heat can still damage the threads over time.

Wool or Wool Blends – Extremely High Risk
Never put wool in a dryer. Heat and tumbling cause wool threads to lock together permanently. This is called hard clumping. The result is a smaller, stiff piece of fabric that cannot be fixed.

How to Dry a Hoodie Safely

Step 1: Read the Care Label First

The label is your first guide. Look for the drying symbol:

A square with a circle inside: Safe to dry in a machine
One dot inside the circle: Low heat
Two dots: Medium heat
A cross over the symbol: Do not dry in a machine

Step 2: Turn the Hoodie Inside Out

Flip your hoodie before putting it in the dryer. This protects the outer fabric. Prints, logos, and smooth surfaces stay safe from direct rubbing and heat.

Step 3: Use Low Heat

Select the lowest heat setting on your dryer. If your machine has an “air fluff” or “no heat” setting, that is even safer. Low heat reduces thread shrinking.

Step 4: Take It Out While Still Damp

Do not let your hoodie become completely dry inside the machine. Pull it out when it is about 80-90% dry. You should feel a slight dampness. Let it finish drying on a rack or hanger in open air.

Step 5: Do Not Overload the Dryer

Clothes need space to tumble freely. When the machine is too full, everything rubs against everything else with more force. This creates more rubbing and uneven drying.

Step 6: Use Dryer Balls (Optional)

Dryer balls help separate fabrics. They reduce clumping and rubbing. Furthermore, they cut drying time, which means less heat exposure.

When You Should Never Use a Dryer

Some hoodies should never go near a dryer:

Wool or wool blend hoodies – Heat causes permanent hard clumping
Hoodies with heavy prints or patches – High heat can crack or peel the design
Labels that clearly show a crossed-out dryer symbol – The maker knows best

Air Drying: The Safest Alternative

If you have time, air drying is always the safest choice.

Flat drying is best. Lay the hoodie flat on a drying rack or a clean towel. Smooth out any wrinkles. Let it dry naturally. This prevents stretching and keeps the shape intact.

Hanging works too, but be careful. Wet hoodies are heavy. Hanging them for too long can stretch out the shoulders. Use a wide hanger if you must hang.

Keep it out of direct sunlight. Sunlight fades colors and weakens threads over time.

Make sure it is completely dry before storing. Any leftover wetness can lead to mildew.

Common Mistakes and FAQs

Common Mistakes

Mistake	Consequence	Fix
Using high heat	Severe shrinking	Use low heat only
Drying until completely dry	Too much shrinking	Remove while still damp
Ignoring the care label	Lasting damage (wool clumping)	Check the label first
Drying right-side out	Faded prints, worn outer fabric	Turn inside out before drying
Overloading the dryer	Uneven drying, more rubbing	Leave space for clothes to move

Frequently Asked Questions

Q: Can I fix a hoodie that already shrank in the dryer?
A: Yes, partly. Soak it in warm water with hair conditioner for 20-30 minutes. Gently stretch it back to size. Lay it flat to dry. This works best on 100% cotton hoodies. Nonetheless, you cannot fully get back the original size.

Q: Is it safe to dry a “pre-shrunk” hoodie?
A: Not fully. Pre-shrinking only lowers the risk. It does not remove it. High heat can still cause more shrinking.

Q: Can I dry a wool hoodie?
A: Never. Wool gets hard clumping when heated and tumbled. The damage cannot be fixed.

Q: Do dryer balls really help?
A: Yes. Dryer balls separate fabrics, reduce clumping, and cut drying time. Less time in the dryer means less heat and less rubbing.

Q: What temperature should I use?
A: Always use low heat. If your dryer has an “air fluff” or “no heat” setting, that is even safer for your hoodie.

Q: I live in a dorm with only a dryer. What should I do?
A: Use the lowest heat setting. Take the hoodie out while it is still damp. Let it finish drying on a hanger in your room. If your hoodie is 100% cotton, be extra careful.
