The Four Contributors
I.
Hormonal
The hormonal influence on follicle behaviour, particularly androgens such as DHT.
II.
Oxidative
Cellular stress on follicle metabolism and the antioxidant defences that counter it.
III.
Structural
The amino acids and minerals that compose the hair fibre itself.
IV.
Stress-related
The relationship between physiological stress and the hair cycle.

DAY SUPPLY
i.
Why morning
Taken in the morning so the daily dose is consistent and easy to remember. The protocol is a habit, not a regimen.
ii.
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.
iii.
Why four
Splitting the daily dose across four capsules keeps each unit swallowable. One capsule could not carry the mass; eight would compromise compliance.
05 · Methodology
How we formulate
A protocol is a moving document. We commit to updating it when the evidence moves.
I.
Evidence-led
Every active is selected from peer-reviewed literature. Doses match the studies they cite. We will not list an ingredient we cannot defend at the dose stated.
Literature-led
II.
Specification-led
Each formulation is published with full doses, sources, and standardisations.
No proprietary blends, no marketing language. The specification is the brand.
No blends
III.
Reformulation by default
Protocols are updated as the evidence develops. Reformulation is the default, not the exception. Subscription customers receive each new revision as it's released
OPEN PROTOCOL
IV.
UK design, GMP manufacture
Formulated in London. Manufactured to GMP standards. Each batch is independently assayed for potency and purity before release.

06 · Questions
Before you commit
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's in it and why each active is at the dose stated. The full rationale is on the methodology page.
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 (a multivitamin, a separate vitamin D supplement, zinc lozenges during cold season, etc.), 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.
Subscription customers receive each new revision as it's released. Each revision is logged with the date and the change.
