Digital perms and humidity
The short answer
A digital permUP usually handles humidity better than a blow-dry, because the wave is in the hair, not styled on top. What humidity brings out is frizz, and frizz comes from dryness, so moisture is the fix.

See WavementUP →Why a perm copes
A blow-dry is a temporary shape: damp air undoes it. A permUP has changed the hair’s shape, so rain and steam don’t make it drop.
Where frizz comes from
Hair that is dry, or a little over-processed, pulls moisture out of the air and swells unevenly. That’s the halo of fuzz on a humid day.
What helps
- Condition every wash and use a leave-in.
- Scrunch in a light cream or gel while the hair is wet, then don’t touch it while it dries.
- Avoid brushing once it’s dry.
When it’s the perm
