Shrinkage, Explained
Shrinkage -- curls pulling up to a fraction of their stretched length as they dry -- looks alarming but is usually a sign of healthy elasticity, not damage. The real question isn't how to stop it, it's how to tell healthy shrinkage apart from the kind caused by over-manipulation or protein overload.

Shrinkage Explained: Is It Actually Damaging Your Hair?
Read itHow much shrinkage is actually normal
Shrinkage scales with curl pattern -- looser 3A/3B curls might shrink modestly, while the tightest 4A-4C patterns can shrink up to 70-75% of their stretched length. That range on its own isn't a red flag; it's simply what elastic, well-hydrated coily hair does as it dries and the curl contracts back into shape.
A simple test to tell healthy shrinkage from a problem
Take a small section of wet hair and gently stretch it between your fingers. Healthy hair will lengthen noticeably and spring back close to its original shape once released -- that bounce-back is the elasticity that makes shrinkage a good sign. Hair that stretches and stays limp, or that snaps rather than springing back, is showing a moisture or protein imbalance, not normal curl behavior, and that's the version worth addressing.
