Overview
KMS made this finishing spray to seal styles against humidity and frizz while adding a weightless shine. Mist it over finished hair to help the look last through damp days.
Long lasting humidity protection with shine helps a blowout or curls look finished for days. Size details conflict in the listing, so the amount is unclear.
Who it's for
People who blow dry or curl their hair and live with humidity get a light sealing spray. Those who need firm hold should pair it with a hairspray.
Pros and cons

- Suits all hair types
- Fresh citrus scent
- Size figures conflict
- No hold level stated
- Directions not listed
Performance notes
The spray forms a light seal over the hair surface, slowing moisture from the air getting in. Shine comes from the same smooth film. Rewashing or heavy sweating removes the seal.
