Where we draw the line

We'll never tell you a scalp ritual regrows pattern baldness, “detoxes” your scalp, or cures a chronic condition like dandruff or seborrheic dermatitis. No solid study backs any of that. And because no one has ever tested massage and herbs as a combined treatment, we won't pretend they “work better together.” What the research does support, we're glad to show you in full.

Everybody's different, so results vary, and none of this is medical advice. If a scalp or hair concern sticks around, please see a doctor or dermatologist.
