  1. Why morning

    Taken in the morning so the daily dose is consistent and easy to remember. The protocol is a habit, not a regimen.

  2. Why with food

    HR01.1 contains fat-soluble actives. Taken with a meal that includes some dietary fat (eggs, avocado, dairy, nuts, or olive oil) absorption is supported by the dietary lipid present.

  3. Why four

    Splitting the daily dose across four capsules keeps each unit swallowable. One capsule could not carry the mass; eight would compromise compliance.

Questions

Before you buy

How long should I take HR01.1 before assessing my response?

Hair grows on its own biological clock. Each follicle cycles through phases of growth, transition, and rest, and a hair shaft grows roughly 1 cm per month during its active phase. New hairs only become visible above the scalp once the previous hair has shed and the new one has grown out, a process that typically takes three months or longer. For this reason, nutritional protocols are evaluated over months, not weeks. We recommend taking HR01.1 consistently for at least three months before assessing your response, and ideally six months for a fuller picture.

Why four capsules?

Each capsule is the largest swallowable format in standard supplement manufacture. Splitting the daily dose across four of them is what allows the formulation to deliver every active at the dose specified. A single capsule could not carry the total mass. Eight capsules would compromise daily compliance. Four is the protocol that holds full doses without asking too much of the routine.

Who is HR01.1 not for?

HR01.1 is intended for adults only. It is not suitable during pregnancy, while planning pregnancy, or while breastfeeding. It is also not suitable for individuals with autoimmune conditions, thyroid disorders, or liver conditions. If you take prescription medication, particularly anticoagulants, blood pressure medication, thyroid medication, diabetes medication, sedatives, or oral contraceptives, consult your doctor or pharmacist before use. The full list of contraindications is on the label.

How is HR01.1 different from a generic hair supplement?

Three things. First, full disclosure. Every active is named and dosed on the label. No proprietary blends. No undisclosed quantities. Second, doses held to the published literature. Where an active has nutritional research behind it, the dose in HR01.1 reflects that research and not a fraction of it. Third, the formulation is a specification. We document what is in it and why each active is at the dose stated.

What if I'm taking other supplements?

Three of the actives in HR01.1 (Vitamin D3, Zinc, and Selenium) have safe upper intake limits set by UK guidance. If you take other supplements containing these nutrients, such as a multivitamin, a separate vitamin D supplement, or zinc lozenges, check the cumulative daily intake to stay within recommended upper limits. The doses in HR01.1 are within the safe range when taken alone.

What happens when the formulation is updated?

Reformulation is the default, not the exception. When the published evidence on an active or a dose moves, the formulation moves with it. Each revision is logged with the date and the change.
