Good to know
What the care can do, how to get started and when we can advise you personally.
24KERATS uses TRICHOPOWER™ with 24 amino peptides. According to the manufacturer, this technology supports repair of the keratin structure. The leave-in mask continues reparative and strengthening care at home.
This does not mean every type of damage is completely reversed: care cannot regrow hair that has already broken off or permanently rejoin split ends. For severely damaged hair, we offer personal advice.
Personal haircare adviceFor the Fast Reconstruction Leave-in Hair Mask at home, leave on for 3 minutes without rinsing. The 2-minute time refers to the separate Reconstruction Hair Mask PRO for professional salon use. Processing time is not a promise to completely reverse all hair damage within that time.
See how to apply the maskNo. For damaged lengths, the leave-in mask is your targeted repair step. Choose suitable cleansing alongside it: Zeolite for frequent washing, or Detox once a week as recommended by our salon. Do not use Detox on a very dry scalp.
