Questions
Before you buy
How long until I see results?
Most men notice reduced shedding within the first several weeks, with more visible change as you stay consistent. Give it a few months of daily use to judge it properly.
Can I use this with minoxidil or finasteride?
Yes. It is a topical, pre-wash treatment with no systemic absorption, so it does not interact with topical minoxidil or oral finasteride. Many men run all three together.
How does the subscription work?
Subscribe and save 15% on every order, shipped on your schedule. Skip, pause or cancel anytime in one click. No traps, no fine print.
What is your shipping and returns policy?
Free U.S. shipping on orders over $75, tracked end to end. If something is not right, reach out and we will make it right.
Who is this for?
Men who want clean, clinically backed grooming that actually does something. Whether your focus is thinning hair, a healthier scalp or dry skin, there is a numbered protocol for it.
Will it work for my hair or skin type?
Yes. The formulas are built for all hair and skin types. They are lightweight, non-stripping and free of the harsh ingredients that cause reactions.
Are the ingredients safe and how are they sourced?
Every active is disclosed in full, with no proprietary blends. Our hair oils are Ecocert COSMOS Organic certified, made with naturally derived ingredients and no parabens, sulfates or endocrine disruptors.
How do I use the full routine?
Reset with H01, feed the scalp with H02, and recover the skin with H03. Each step takes about two minutes. Use the Complete Scalp Protocol to run the core routine together and save.
