Made in the USA.

What it is. ZERO GRAY is a daily formula that supports your hair's natural color by working where gray starts: the pigment process inside the follicle. Two capsules a day.

How it works. Catalase supports the breakdown of hydrogen peroxide, the build-up linked to graying. L-tyrosine and PABA are the raw materials of melanin. Fo-ti root, L-methionine, biotin, pantothenic acid, B6, B12, folate, iron and selenium support healthy hair growth and strength.

What's in it. Vitamin D, B6, folate, B12, biotin, pantothenic acid, iron and selenium, plus a 1,050 mg complex of PABA, L-tyrosine, L-methionine, catalase and fo-ti root. Vegetarian capsule. 60 capsules, a 30-day supply.

Made the Newt way. Manufactured in the USA in a GMP-certified facility, with every batch tested by an independent third-party lab for identity, purity and potency.

Serving size: 2 capsules. Per serving: Vitamin D 50 mcg (as cholecalciferol), Vitamin B6 13 mg (as pyridoxine HCl), Folate 770 mcg DFE (450 mcg L-5-MTHF), Vitamin B12 10 mcg (as methylcobalamin), Biotin 450 mcg, Pantothenic acid 350 mg (as D-calcium pantothenate), Iron 18 mg (as ferrous fumarate), Selenium 110 mcg (as selenomethionine), ZERO GRAY Complex 1,050 mg: para-aminobenzoic acid (PABA), L-tyrosine, L-methionine, catalase, fo-ti root extract.

Other ingredients: vegetable cellulose (capsule), rice flour, silica. Vegetarian capsule. Non-GMO, gluten free, no artificial coloring.

Take 2 capsules once daily, with or without food; the iron is easier on the stomach with food. Color shows in new growth, so plan on 3 to 6 months of daily use. Do not exceed the suggested serving.

Gray starts in the follicle. Start there.

Hair goes gray when the follicle stops producing melanin and hydrogen peroxide builds up at the root. ZERO GRAY supplies the enzyme that breaks peroxide down, the amino acids melanin is made from, and the vitamins and minerals healthy hair depends on.

Peroxide defense. Catalase supports the follicle's own system for breaking down hydrogen peroxide, the build-up linked to graying.

Melanin building blocks. L-tyrosine and PABA are raw materials of melanin, the pigment that gives hair its color.

Hair nutrition. Biotin, pantothenic acid, B6, B12, folate and iron support healthy hair growth and strength.

Traditional support. Fo-ti root (He Shou Wu) has a long history of traditional use for hair, and L-methionine supports keratin.

"Others" reflects common practice among mass-market supplement brands. Always compare labels.

What to expect, and when.

Color is set when a hair forms, so any change shows in new growth at the root, not in hair that has already grown out. Plan on 3 to 6 months of daily use. Individual results vary, which is why every bottle is covered by our money-back guarantee.

MONTH 1

Building up

Catalase, tyrosine and B-vitamin levels build. Hair that has already grown stays as it is.

MONTH 2–3

Watch the roots

New growth forming on the formula is where any change shows first.

MONTH 4–6

The long game

A full cycle of new growth on the formula is when color support becomes noticeable. Keep taking it daily to hold it.

I wanted proof, not promises. So I built Newt.

Newt started with three questions I asked every brand I was buying from: what’s the exact dose, who tested it, and can I see the report? Not one of them answered all three. So I built the brand that would.

Here are Newt’s answers, for every product we make. The dose isn’t my opinion — it’s the one used in the published clinical studies. The testing is done by an independent, ISO 17025-accredited lab, and every product is made in an FDA-registered, cGMP facility.

My job is the part most of this industry skips: making sure all three happen every single time, and showing you the proof. When someone takes something you made, “close enough” isn’t a standard.

Every product we make is something I’d take myself and give to my family. Trust should be earned with evidence, not promises.

Have a question? Get in touch. I personally read and respond to every message.

Questions before you order.

Will it turn my gray hair back to my natural color?

It supports the pigment process in hair that is forming now, so any change shows in new growth at the root. Hair that is already gray and grown out won't change color. How much changes depends on genetics and how long the follicle has been gray, which is why we say 3 to 6 months and offer a guarantee.

How long does it take?

Hair grows about half an inch a month, so expect to judge it by the roots after 2 to 3 months and the overall effect at 6.

Does it contain iron?

Yes, 18 mg per serving (100% of the Daily Value). If you already take iron or a multivitamin with iron, don't double up without talking to your physician.

Can I take it with FullHead?

Yes, with one caveat: together they provide 5,000 IU of vitamin D, just over the 4,000 IU daily upper limit, so don't add a separate vitamin D, and check with your physician if you take both long-term. Combined selenium (330 mcg) stays under the limit.

Can women take it?

Yes, adults of any gender who are not pregnant or nursing.

What happens if I don’t see results?

Every order is covered by our money-back guarantee. Contact support and we'll take care of it.
