How to Fix an Itchy Jumper
2. When the sweater is still damp, massage it with a good hair conditioner—the cheap stuff will cause a waxy buildup. Try to avoid stretching the sweater’s fibres when you do this.
3. Give the conditioner 30 minutes to set on the sweater, and then rinse all of it out with cold water. Press gently on the sweater to remove the rest of the water, taking care not to lose its shape.
4. Place the sweater on a towel and let it dry flat. When it’s completely dry, fold it neatly and put it in a large zip-top plastic bag.
5. Place the bagged sweater in the freezer overnight, and in the morning, it won’t itch anymore. The conditioner and the vinegar make the fibres in the sweater softer, and freezing it prevents its short fibres from poking out.
