Common Questions

Before you start

Yes — anytime, no penalties. Manage everything from your account dashboard. Skip a shipment, delay it, swap a product, or cancel with one click.
Yes. The Renew Hair Growth Serum is safe for sensitive scalps and for daily use. Mild tingling or warmth in the first week is normal as follicle activity increases. If irritation persists, reduce to every other day for 7–10 days, then build back to daily.
You'll receive a welcome email with Dr. Truesdale and Dr. Drummond's AM/PM routine guide, a 30/60/90-day expectations guide, and access to his getting-started video.
Approximately 1 month with consistent daily use — which is why every 30 days is the default subscription cadence.
