Technique frizz happens when the routine itself is fighting the curl. Brushing dry, rubbing with a terry towel, applying product on damp instead of soaking wet hair, or touching curls while they dry: each one breaks the cuticle and disrupts the curl clump. You probably already own everything you need. The fix is a sequence change, not a shopping trip.
Most of this is tools, not products. The product you have probably works once the application changes.
Scrunchie reads your hair from a daily photo and adapts the routine to attack technique frizz specifically. The fix you just diagnosed, executed every day.
The app reads your hair from a daily picture: definition, frizz halo, dryness, volume.
