Grey is when the colour mixing stops.

Every hair colour is two pigments, dark and red, mixed at the root. NYU Langone found the cells behind it don’t die. They get stuck. Anti Grey 1.0 is two capsules a day, built around that research.

The evidence behind the window.

Five chapters tracing the science, compounds, computation, Batch 001 response, and advisory review behind Anti Grey 1.0.

§ 01

Observed outcomes.

What the first respondent corpus reported after months 3–6 on protocol.

OBSERVED OUTCOMES · BATCH 001 n = 60 · months 3–6 on protocol

Less new grey 92%

Thicker, fuller hair 89%

Less shedding 87%

Stronger, less brittle 76%

0 25 50 75 100

Voluntary reviewer corpus · standardised question set · oral protocol only.

METHOD

Batch 001 respondent corpus collected Nov 2025–Apr 2026. Sixty respondents answered the same standardised question set at months 3–6 on oral protocol. The four outcomes shown are the four questions asked; none are withheld.

CONTINUITY

Batch 001 is the first respondent corpus: n = 60 on the standardised question set, months 3–6 on protocol, oral protocol only. The same question set carries into Batch 002.

§ 02

Clinical evidence.

The published papers the protocol is built on. Four landmark findings on the biology of grey; compound-level evidence for the interventions Hair Labs uses to answer it.

The findings that opened the window

Sympathetic nerve hyperactivation depletes melanocyte stem cells.

Zhang et al · Nature · Harvard · 2020

Identified the first direct mechanism: stress-driven noradrenaline exhausts the stem cells responsible for hair colour. The paper that established stress as a cause of grey, not a correlate.

Ashwagandha · Rhodiola

Greying is reversible when the stressor is removed.

Rosenberg et al · eLife · Columbia · 2021

Mapped grey and pigmented segments of individual human hairs to documented periods of psychological stress. When stress was removed, pigment returned along the same shaft. The first direct evidence of a reversibility window.

Protocol-level

Melanocyte stem cells do not die when colour fades — they become stranded in the hair germ.

Sun et al · Nature · NYU Langone · 2023

The stem cells that produce pigment remain present in ageing follicles but fail to return through the dedifferentiation cycle that normally maintains the reserve. The failure mode is signalling, not cell death — which opens a reversibility window every formulation written before 2024 had no way to address.

Reserve

Luteolin preserves the signalling between keratinocyte and melanocyte stem cells.

Iida et al · Antioxidants · Nagoya University · 2024

Oral and topical luteolin preserved endothelin signalling in the hair germ and suppressed p16^ink4a + senescent keratinocytes in the bulge. Hesperetin and diosmetin, two structurally similar flavonoids tested in the same study, produced no effect. The first anti-greying result for an oral flavonoid in a model engineered to reproduce the human failure mode.

Luteolin 100 mg

The compound-level evidence

Ashwagandha reduces serum cortisol by 27.9% vs placebo.

Chandrasekhar et al · Indian Journal of Psychological Medicine · 2012

Double-blind, randomised, placebo-controlled. 300 mg standardised Withania somnifera root extract, twice daily for 60 days. The register-level proof that ashwagandha produces a measurable cortisol effect at this dose.

Ashwagandha 300 mg

Rhodiola blunts the cortisol awakening response.

Olsson et al · Planta Medica · 2009

Randomised, double-blind, placebo-controlled across 60 adults with chronic stress-related fatigue. Rhodiola rosea extract reduced the cortisol spike that follows waking and improved sustained attention over 28 days.

Rhodiola rosea 100 mg

Cobalamin and Folate status is significantly lower in premature greying.

Daulatabad et al · International Journal of Trichology · 2017

Case-control study. Premature greying patients showed significantly reduced serum cobalamin and folate vs age-matched controls. Both are required cofactors in the methylation-dependent steps of melanin biosynthesis.

Cobalamin 100 µg · Folate 400 µg

Copper status is significantly lower in premature greying.

Bhat et al · Biological Trace Element Research · 2013

Premature greying patients had significantly lower serum copper (p = 0.048) vs controls. Copper is the essential cofactor for tyrosinase — the enzyme that catalyses the rate-limiting step of melanin synthesis.

Copper Gluconate 1.5 mg

Materia Medica.

Each ingredient named with its source species. Every dose named at its published clinical level. Every pair modelled for interaction.

Luteolin

from Sophora japonica · flower bud

Dose: 100 mg
Standardised to: ≥ 98% purity (HPLC)
Pharmacopoeia: TCM — huai hua

Preserves endothelin signalling between keratinocyte and melanocyte stem cells; suppresses p16^ink4a + senescent keratinocytes in the bulge. Regenerated in cycle by ascorbate.

Iida et al, 2024.

Ashwagandha

from Withania somnifera · root

Dose: 300 mg
Standardised to: ≥ 5% withanolides
Pharmacopoeia: Monographed

Buffers the chronic cortisol load that pushes follicles prematurely from anagen into telogen. Double-blind RCT: −27.9% serum cortisol vs placebo at 60 days.

Chandrasekhar et al, 2012.

Rhodiola

from Rhodiola rosea · root

Dose: 100 mg
Standardised to: ≥ 3% rosavins · ≥ 1% salidroside
Pharmacopoeia: EMA HMPC · monographed 2012

Blunts the cortisol awakening response; handles acute stress peaks between ashwagandha’s slower tonic buffering.

Olsson et al, 2009.

L-Tyrosine · Copper Gluconate

Pharmaceutical amino acid · pharmaceutical mineral salt

Dose: L-Tyrosine 500 mg · Copper 1.5 mg
Form: Free-form amino acid · copper gluconate salt
Role: Melanin substrate · tyrosinase cofactor

L-Tyrosine is the precursor melanin synthesis consumes; copper is the catalytic metal tyrosinase requires. Neither is useful without the other. Supplied together.

Bhat et al, 2013.

Vitamin complex

Cobalamin · Folate · Pyridoxine · Choline · Biotin · Pantothenic Acid

Dose: Cobalamin 100 µg · Folate 400 µg · Pyridoxine 10 mg
Co-dose: Choline 100 mg · Biotin 5 mg · Pantothenic Acid 50 mg
Role: Methylation lane · keratin cross-linking

Keeps the one-carbon metabolism lane melanocytes depend on running; supports the keratin cross-linking that resists mid-shaft fracture.

Daulatabad et al, 2017.

Ascorbic Acid

Pharmaceutical vitamin

Dose: 100 mg
Form: L-ascorbic acid
Role: Redox partner · collagen cofactor

Regenerates the reversible oxidised intermediates of luteolin, returning it to its reduced parent form; supports the collagen synthesis strands depend on for structural integrity.

§ 04

The computation.

Five active-core compounds and the Co-Factor Circuit do not fit together by accident. Anti Grey 1.0 was resolved by pairwise interaction modelling against five constraints at once.

01

Redox compatibility.

Each antioxidant must regenerate its partners rather than oxidising them. Luteolin and ascorbate were selected because the catechol B-ring of luteolin forms reversible semiquinone intermediates that ascorbate is competent to reduce — a working redox cycle, not two separate antioxidants.
02

Cofactor dependency.

Melanin biosynthesis requires Copper for tyrosinase and the one-carbon lane for methylation; neither is useful alone. The formulation resolves the cofactor graph so every substrate has its catalyst and every catalyst has its lane.
03

Methylation-lane fit.

Cobalamin, folate, pyridoxine, and choline run the one-carbon metabolism lane melanocytes depend on. The doses are ratio-fitted to each other, not only to their own published targets, to avoid the homocysteine imbalance a single nutrient at a clinical dose can produce.
04

Absorption and form.

Every compound is carried in the chemical form its clinical evidence used — luteolin as its aglycone, ashwagandha as a standardised withanolide extract, copper as the gluconate salt. No methylated or proprietary form smuggles a different pharmacology in under a name the evidence never tested.
05

Two-capsule discipline.

The above four constraints were resolved against a fifth: everything has to fit inside two capsules a day. Most formulations solve the first four by asking for four, six, eight capsules. Anti Grey 1.0 solves them at two.

WHAT THIS MEANS

Pairwise interaction modelling is the reason Anti Grey 1.0 can be read as five NooPigment Matrix™ compounds, supported by the Co-Factor Circuit, and also as a single integrated protocol. The dose of any one compound is not chosen in isolation; it is chosen against the rest of the system. When the published literature produces a new compound worth adding, the computation is re-run, not bolted on. The research surface is where this is shown in full.
