Frequently Asked Questions

1. How do I sequence my Hiro Protocol?

Our protocols are numbered to make daily routine optimization completely seamless:

H01 Root Revival (Scalp Oil): Apply directly to the scalp daily or as a pre-wash treatment, massaging thoroughly.
H02 Morning Glow (Vitamin C Serum): Apply 2 pumps on clean, dry skin every morning before applying your daily sunscreen.
H03 Night Repair (Ceramide Moisturizer): Apply as the final step of your evening routine to lock in overnight moisture and repair the barrier while you sleep.

2. Are your products suitable for sensitive skin or scalps?

Yes. Our formulations are built on nourishing botanical oils, squalane, and skin-identical lipids like ceramides which are highly biocompatible. However, because skin types are highly individual, we expect and advise all clients to perform a 24-hour patch test on a small, discreet area before full use to ensure complete compatibility.

3. What is your shipping timeline?

We process all in-stock orders within 1 to 2 business days. Standard standard shipping typically takes 3 to 5 business days to arrive once dispatched. We currently ship within the United States only.

4. What is your return and refund policy?

Due to the personal care nature of our small-batch formulations, we offer a strict 7-day return and refund window from the date of delivery. Returned items must be completely unopened, unused, and in their original packaging. Please reach out to us at hello@hiroprotocol.com within 7 days of delivery to initiate a return.

5. Do your formulations contain artificial fragrance or harsh fillers?

No. We strictly avoid parabens, sulfates, artificial fragrances, endocrine disruptors, or cheap synthetic fillers. You get only functional actives and botanical nutrients at therapeutic concentrations.
