FullyVital vs. Arey: An Honest Anti-Gray Comparison

If you're comparing FullyVital and Arey, you want a straight answer.

Both brands target gray hair at the root — not with dye, but with nutrients and actives.

The biggest difference: FullyVital is a two-product inside-and-outside system, while Arey focuses primarily on a daily supplement.

Key fact: In an April 2025 customer survey, 85% of FullyVital users reported noticing fewer grays after 90 days of consistent use.

If you've been paying $200+ a month at the salon and wondering whether something smarter exists, this comparison is for you.

What Does Each Brand Actually Do?

FullyVital is a two-part system: a daily supplement and a scalp serum.

Together, they're designed to support your hair's natural melanin production from the inside and the outside at the same time.

Arey offers a daily supplement — their "Not Today, Grey" — and a topical hair mist they call "Grey Delay."

Both brands take a root-cause approach rather than masking gray with dye.

Ingredient Comparison: What's Inside Each Formula?

The ingredient list is where the real difference lives.

FullyVital's Supplement Stack

FullyVital's supplement includes copper (1mg) — an EU-authorized nutrient that contributes to normal hair pigmentation.

It also provides L-Tyrosine (400mg), the building block your body uses to support natural pigment production.

GliSODin (250mg) helps support your body's own antioxidant defenses against the oxidative stress tied to aging hair.

Rhodiola and L-Theanine are adaptogens that support your resilience to everyday stress — the same stress research links to graying.

A full B-complex (B5, B6, B12, Folate) supports healthy hair from within, alongside zinc, selenium, biotin, glutathione, astaxanthin, and Polypodium.

Arey's Supplement Stack

Arey's "Not Today, Grey" supplement centers on catalase, an enzyme that breaks down hydrogen peroxide in the follicle.

It also includes copper, biotin, zinc, and a selection of B vitamins.

The overlap in core nutrients is real — copper and B vitamins appear in both formulas.

Where they diverge: FullyVital adds the adaptogen complex (Rhodiola, L-Theanine), GliSODin, and the multi-antioxidant blend that Arey's formula doesn't include.

FullyVital's Serum vs. Arey's Topical Mist

FullyVital's serum is formulated with 2% Greyverse — a clinically-studied α-MSH biomimetic peptide designed to support the hair's natural pigment process.

It also contains Silverfree (1.5%), which helps reduce the hydrogen-peroxide buildup associated with graying.

Arcolys (1%) helps target oxidative stress in the follicle to support your hair's natural color.

Arey's "Grey Delay" mist is a lighter-format topical; its key actives include saw palmetto and a smaller peptide blend.

The FullyVital serum is applied directly to the scalp — where the follicle lives — rather than distributed through the lengths of the hair.

The 5 Root Causes: How Each Brand Addresses Them

FullyVital is designed to target what it calls the 5 root causes of graying.

Understanding them makes the comparison clearer.

Arey addresses two or three of these causes well — oxidative stress and peroxide buildup in particular.

FullyVital is designed to work across all five at once, and adds the topical serum as a second delivery mechanism directly at the scalp.

Formulator Credentials

FullyVital was formulated by Dr. Sandra Kaufmann, MD — a cellular biologist and longevity expert.

The formula reflects her background in cellular aging mechanisms, not just cosmetic marketing.

Arey was co-founded with input from colorists and wellness practitioners.

Both brands are vegan and cruelty-free; FullyVital is also third-party tested for heavy metals, non-GMO, GMP-certified, and made in an FDA-registered US facility.

What Real Users Are Saying About FullyVital

Jen H. writes: "My stylist has been amazed by the reduction in my grays — love these products!"

Shana G. adds: "I see much less grays in the mirror — I don't have to dye my hair for 14 weeks now."

FullyVital holds a 4.7 / 5 average rating across more than 21,600 customers.

Which One Is Right for You?

If you want a supplement-only approach with a light topical option, Arey is a reasonable starting point.

If you want a system designed to support all five root causes — with a clinically-studied serum applied directly to the scalp and a broader-spectrum supplement — FullyVital is the more comprehensive choice.

And if you've already tried supplements that didn't move the needle, the addition of the serum is the meaningful variable.

FullyVital's 120-day money-back guarantee means you can try it for four full months, risk-free.

If you're not seeing results, they'll refund you — no questions.
