Anti-Gray Serum Ingredients, Fully Explained

The label tells you what is in the bottle.
It does not always tell you what each ingredient actually does.
The FullyVital Anti-Gray Serum is built on a specific set of actives, each targeting a different root cause of graying at the scalp level.
This page explains every one of them, plainly.
Key fact: A 2009 study published in FASEB Journal found that hydrogen peroxide accumulates in aging hair follicles as the enzyme catalase declines.

What is the FullyVital Anti-Gray Serum, and how does it work?
The Anti-Gray Serum is a leave-in scalp serum designed to support your hair's natural pigment process from the outside in.
It is formulated to target three of the five root causes linked to graying at the follicle level.
Those three are oxidative stress (the buildup of damaging free radicals in the follicle), hydrogen peroxide accumulation (a specific oxidant that builds up as certain enzymes decline with age), and stem-cell aging (the gradual decline of the scalp environment that supports pigment-producing cells).
The serum works alongside the Anti-Gray Supplement, which addresses the same root causes from the inside through nutrients like copper, L-Tyrosine, and a multi-antioxidant complex.
Used together, the two formulas are designed as an inside-and-outside system.
Used alone, the serum is still a meaningful step for anyone who wants to start addressing the scalp environment directly.

What is Greyverse, and why is it the lead ingredient?
Greyverse is a patented peptide active (Palmitoyl Tetrapeptide-20) included at 2% in this formula.
It works as an alpha-MSH biomimetic, meaning it is designed to mimic a signaling molecule your body uses to activate melanin production in the follicle.
Alpha-MSH (alpha-melanocyte-stimulating hormone) is part of the natural pathway your body uses to tell pigment cells to produce color.
As that signaling weakens with age, the follicle produces less melanin.
Greyverse is formulated to support that pathway and promote the look of fewer grays.
The 2% concentration is the level at which the supplier conducted its supporting studies.
This formula uses that exact level, not a trace amount.
What does Silverfree do in the serum?
Silverfree is included at 1.5% and targets the hydrogen peroxide problem directly.
As hair follicles age, the enzyme catalase (which normally breaks down hydrogen peroxide) becomes less active.
The result is a slow buildup of hydrogen peroxide inside the follicle.
A 2009 study published in FASEB Journal showed this mechanism is closely tied to the graying process, specifically through its effect on methionine sulfoxide repair in pigment cells.
Silverfree is designed to help reduce that hydrogen peroxide buildup associated with graying.
EUK-134, also in the formula at 0.01%, complements Silverfree.
It is a SOD/catalase-mimetic antioxidant, meaning it is designed to mimic the function of the two enzymes that naturally defend the follicle against peroxide and free radicals.
What is Arcolys, and what does it target?
Arcolys is included at 1% and targets oxidative stress in the follicle specifically.
Oxidative stress refers to damage caused by an excess of free radicals (unstable molecules that damage cells when they accumulate faster than the body can neutralize them).
Research published in FASEB Journal in 2006 proposed a "free radical theory of graying," linking melanocyte apoptosis (pigment-cell death) in aging follicles to oxidative stress-induced tissue damage.
Arcolys is formulated to help target this same oxidative stress to support your hair's natural color.
What is Melanogray?
Melanogray is an upcycled active derived from Chios mandarin, included at 1%.
It is studied to support the look of fewer gray hairs.
It works within the melanin-pathway group alongside Greyverse and Arcolys, supporting the follicle's ability to sustain natural pigment production.

What does Eterwell Hair do?
Eterwell Hair is a senolytic active included at 2%.
Senolytics (compounds studied for their role in clearing aged, dysfunctional cells) are an emerging area of scalp aging science.
As the scalp ages, certain cells stop functioning properly but do not clear away on their own.
This can affect the stem-cell environment that supports healthy follicle activity.
Eterwell Hair is designed to help support that scalp stem-cell environment as hair ages.
What are Capilia Longa and Panax Ginseng doing in this formula?
Capilia Longa (0.5%) and Panax Ginseng (0.3%) are botanical actives that support a healthy scalp environment for vital-looking hair.
A well-functioning scalp environment is a foundation for the other actives to work within.
Ginseng in particular has a long history of use in hair and scalp support.
What about copper peptides, keratin, and panthenol?
Copper peptides at 0.01% support scalp and follicle condition.
The role of copper in hair pigmentation is one of the most well-established in this space.
The European Food Safety Authority confirmed in 2009 that copper contributes to normal hair pigmentation, one of very few EU-authorized hair-color health claims.
Hydrolyzed keratin (broken-down keratin proteins) and DL-Panthenol (a form of vitamin B5) round out the formula for texture and condition.
They provide instant smoothness, body, and shine while the other actives work at the follicle level.
What is Fo-Ti, and why is it included?
Fo-Ti (Polygonum multiflorum, at 0.1%) is a botanical with a long history in Chinese herbalism for supporting hair color and vitality.
It is included in this formula as a traditional complementary ingredient alongside the clinically-studied actives.
How do the serum ingredients compare at a glance?

Note: "—" in the concentration column indicates the ingredient is present as a conditioning complex rather than at a precisely disclosed percentage.
How do you use the serum to get the most from these ingredients?
Apply the serum directly to the scalp, not the lengths of the hair.
The actives are designed to work at the follicle level, which sits at the scalp surface.
Use it consistently, once daily or as directed on the packaging.
Hair grows in cycles, and the follicle needs sustained support to show a change in the hair that has already emerged.
Most customers who see results report noticing them between 60 and 90 days.
In a customer survey completed in April 2025, 88% of FullyVital customers reported seeing new pigment at the roots in 60 days.

Is the serum enough on its own, or do you need the supplement too?
The serum addresses the root causes that can be reached through the scalp.
The supplement addresses those same root causes from the inside, through nutrients your follicles depend on.
Using both together is the design intent, and the data behind the 85% and 88% customer results reflects customers using the system.
That said, the serum is still a meaningful standalone step, especially if you are already taking a high-quality hair supplement and want to add a targeted topical.
If you are ready to address both sides at once, the Anti-Gray 30-Day Kit pairs the serum and the supplement in one system.

FullyVital backs the system with a 120-day money-back guarantee.

Frequently Asked Questions
What is the main active ingredient in the FullyVital Anti-Gray Serum?
Greyverse (Palmitoyl Tetrapeptide-20) is the lead active, included at 2%.
It is formulated to support the hair's natural pigment signaling pathway and the look of fewer grays.
The formula pairs it with Silverfree, Arcolys, Melanogray, EUK-134, and Eterwell Hair, each targeting a different root cause of graying.
Does the serum contain copper?
Copper peptides are included at 0.01% to support scalp and follicle condition.
Copper plays a well-established role in normal hair pigmentation.
The European Food Safety Authority authorized a claim linking copper to normal hair pigmentation in 2009, one of very few EU-approved hair-color claims in existence.
What does Silverfree do?
Silverfree is designed to help reduce the hydrogen peroxide buildup associated with graying.
Hydrogen peroxide accumulates in aging follicles as the enzyme catalase becomes less active.
This buildup is one of the recognized biological drivers of the graying process.
Silverfree works alongside EUK-134, a catalase-mimetic antioxidant, to support the follicle's defenses against this buildup.
Is this serum safe for color-treated hair?
The serum is vegan, cruelty-free, and drug- and hormone-free.
It is third-party tested for heavy metals and made in an FDA-registered, GMP-certified facility in the USA.
It is formulated as a leave-in scalp serum, not a hair dye or bleaching agent, so it does not strip or alter existing color.
If you have a specific scalp sensitivity, review the full ingredient list or consult your dermatologist.
How long does it take to see results from the serum?
Hair grows in cycles, and change at the follicle level takes time to show up in the hair shaft.
In a customer survey completed in April 2025, 88% of FullyVital customers reported seeing new pigment at the roots within 60 days.
Consistency over a full growth cycle (around 90 days) is how you give the formula a fair opportunity to work.
