Preventing Dryer Shrinkage
Shrinkage prevention concerns the entire care sequence, including the dryer. Heat and movement can stress vulnerable clothing after a careful wash, and a low setting is relevant only where tumble drying is allowed. Read the drying instruction separately, avoid unnecessary exposure, and do not rely on a later reshaping remedy to restore every garment completely.
Two stresses act together
Homes & Gardens discusses high temperatures and the dryer's movement as contributors to shrinkage in vulnerable fabrics. The article focuses on protecting clothing through suitable settings and alternative drying methods. A successful wash is not permission to expose an item to a stronger drying process.

Recovery has limits
The source cautions that a shrunken garment may not return exactly to its former state, even where careful reshaping helps. Prevention therefore deserves more attention than a promise to reverse damage later. Check the care label and select a compatible drying method before the item enters the drum rather than relying on a remedy after the fact.
