The short answer is no—cashmere does not shrink every time you wash it, but improper care can lead to shrinking. Cashmere is a natural fiber made from the soft undercoat of goats, and while it’s luxurious and durable, its delicate nature demands gentle handling to maintain its size, shape, and softness.
Why Does Cashmere Shrink?
Cashmere is prone to shrinking due to its natural fibers’ reaction to heat, water temperature, and agitation. Here’s what can cause it to shrink:
- Hot Water – Washing cashmere in hot water can cause the fibers to tighten and shrink.
- Aggressive Agitation – Rough handling, such as machine washing on a regular cycle, can damage the delicate fibers.
- Tumble Dryers – Heat from a dryer can lead to irreversible shrinking.
How to Prevent Shrinking When Washing Cashmere
To keep your cashmere garments soft, beautiful, and true to size, follow these steps:
- Hand Wash with Care
Fill a basin with lukewarm or cool water and add a gentle detergent, such as one specifically designed for wool or delicate fabrics. Gently swirl the item in the water—do not rub or wring it.
- Avoid Heat
Always use cool or lukewarm water when washing cashmere and avoid exposing it to high temperatures.
- Rinse and Press Gently
After washing, rinse in clean, cool water, then gently press out excess water without twisting or wringing the fabric. Use a towel to roll the item and absorb remaining moisture.
- Lay Flat to Dry
Reshape the garment and lay it flat on a clean, dry towel to air dry. Hanging cashmere can cause it to stretch out of shape.
- Store Properly
Store your cashmere folded rather than hung to prevent stretching, and keep it in a cool, dry location.
What If Your Cashmere Already Shrunk?
If your cashmere has already shrunk, you may be able to gently restore it:
- Fill a basin with lukewarm water and add a small amount of hair conditioner or wool-specific detergent.
- Place the shrunken piece in the water, allowing it to soak for about 30 minutes to soften the fibers.
- Gently stretch the garment back to its original size while it’s damp. Lay it flat to dry, reshaping as needed.
Cashmere is an investment, and with proper care, it can last for years without shrinking. Treat it gently, and it will reward you with softness and elegance every time you wear it!
