Okay, so you’ve shrunk a sweater in the laundry. We've all done it. It’s hopeless, right? Not necessarily. There might be a chance to save it. Follow these instructions and you may end up with a wearable sweater, even if it has been a while since you shrunk it.
Unshrink Sweater Home Remedy
Fill a sink with room temperature water and dissolve in a few teaspoon of hair conditioner. Just about any brand will work, just make sure it's not a shampoo and conditioner combination or shampoo plus. The soap in those will work against you. Soak the sweater in the solution for 5-10 minutes. Then lay it out on a large dry towel. Gently stretch the sweater into its original shape and size. Be very careful to stretch it evenly. Let it dry completely in that position. Knitters use a similar technique when blocking a sweater. It doesn’t work in every scenario but many sweaters can be saved. I saved my favorite Woolrich Sweater one this way!
