Questions, answered.
What is PROTOKODE? What do you sell?
A three-step routine: Peptide Density Scalp Serum (30 mL, nightly), Lactic Clarifying Scalp Exfoliant (30 mL, once or twice a week) and Keratin Strengthening Hair Mist (100 mL, after washing). Start with the Serum.
Where should I start? Which supply should I choose?
Start with the Serum. We suggest the 3-Month Supply (free Exfoliant, free shipping); the 6-Month is the best value per month, and the 1-Month is the smallest way to try it.
Do I need all three products for it to work?
No. The Serum works on its own; the Exfoliant clears buildup and the Mist leaves strands looking smoother and shinier, so add them whenever you like.
Is it a subscription? Will it renew?
No. Every order is a one-time purchase, so nothing renews; just place a new order when you need more.
Where do you ship and how fast?
Anywhere in the US except Alaska, Hawaii, US territories, military addresses and PO boxes. Orders usually ship within 1–5 business days, with a tracking link for every box.
What is your returns policy?
Every order arrives right. If anything arrives damaged, defective, wrong or missing, email us photos within 14 days and we'll replace it free. If your parcel is lost on the way, we'll send a replacement. Because these are personal-care products, we can't take returns or refund change-of-mind purchases, opened or unopened.
