No, and we won't claim it is. Protocol 01 is a cosmetic system that works on scalp condition and the environment around the follicle. It is designed to sit alongside whatever else you do, or to be the thing you do before you consider anything pharmaceutical. If you want a prescription pathway, a dermatologist is the right call and we will say so.

Scalp comfort and flaking typically change within two to three weeks. Anything relating to hair itself moves on the growth cycle, which means 12 weeks is the earliest honest assessment point and 24 weeks is a better one. This is why the return window is 90 days rather than 30. Photograph your part line on day one under the same light.

Because a proprietary complex at an undisclosed concentration is unfalsifiable, and you cannot evaluate what you cannot see. Publishing the numbers means you can check our doses against the literature yourself. It also means we cannot quietly cut a cost by reducing an active, which is the more useful discipline.

You receive three refill cartridges every 90 days at $62. The bottle and applicator from the first shipment are yours permanently, so subsequent shipments are formulation only. You can change the interval, skip a cycle, or cancel from your account without contacting anyone.

The protocol treats the scalp rather than the hair shaft, so the actives behave the same across hair types. Texture affects step 03 only: if your hair is coarse or tightly coiled, use the full 2ml and leave it overnight. If it is fine or straight, 1ml is usually enough to avoid weight the next morning.
