Korean user insights

What Korean shoppers say about this product

Korean buyers treat this as an easy daily scalp mist. The most repeated points are that it does not leave hair greasy or weighed down, that it feels cool and calming after washing or blow-drying, and that itching and dye-sensitised scalps feel more comfortable within a week or two. The recurring complaints are an unreliable spray nozzle and a 100ml bottle that regular users empty quickly.

Commonly praised

  • Leaves no greasy or weighed-down feeling on hair
  • Cooling, calming sensation after washing or blow-drying
  • Reported to ease scalp itching and dye-sensitised discomfort
  • Spray format is simple enough for daily use

Worth knowing

  • Several buyers report a stiff or dribbling spray nozzle
  • Daily users say the 100ml bottle runs out fast and want a larger size
  • Opinions on visible hair change are cautious; many say it is too early to tell

  1. Silas Vale Nashville, United States

    The biotin and ceramide in this tonic serum really help my scalp feel less tight after a day in Nashville humidity.

  2. Elsa Sjöberg Uppsala, Sweden

    Luktar svagt av frisk ört och känns sval, inte kladdig, på hårbotten.
