Shrinkage

TheWashDay editorial · Updated October 13, 2026 · From the American Academy of Dermatology · How we compare

Jump to a section

Shrinkage is the way curls and coils spring up as they dry, so hair looks much shorter than its stretched length. It comes from the curl pattern itself, so it isn’t a sign of damage, though it doesn’t show your hair is undamaged either; tighter patterns, such as type 4 hair, shrink the most. If you want to show length, stretch the hair while it dries: twists, braids, banding or a low-heat blow-dry with a heat protectant.

How to detangle

That is a wash-and-go: gel on wet hair, as wet as its label asks.

What to look at

Compare a clean, wet strand pulled straight with the same strand dry. The bigger the difference, the tighter the pattern. Shrinkage varies across the head and from day to day with humidity.

Change one thing on your next wash

If you want length, pick one way to stretch on your next wash:

Two-strand twists or braids on damp hair, left to dry fully, then undone.
Banding: hair ties placed every few inches down each section while it dries.
African threading: wrapping sections with thread while they dry.
Blow-drying on low heat with a heat protectant, in sections, with the dryer pointed down the hair.
A stretched wash-and-go: style in sections and pull each section gently as it dries.

When this is not the answer

Shrinkage is not something to fix unless you want a stretched look. Constant stretching with heat damages hair over time; the American Academy of Dermatology advises the lowest heat setting that works and pressing no more than once a week.

Products that do this job

A heat protectant matters if you stretch with a blow-dryer; a gel holds a defined, shrunken style.
