Gray hair is a biological reality for most, driven by a gradual decline in catalase production within hair follicles, which allows hydrogen peroxide to accumulate and bleach the hair from the inside out. While dye boxes promise instant cosmetic fixes, the real battle happens at the cellular level, and the market is flooded with treatments that either mask the problem or make dubious claims about reversing it.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years analyzing the ingredient profiles, clinical backing, and real-world user feedback on anti-gray supplements and topical treatments to separate the science from the marketing fluff.
This guide breaks down the five most viable contenders for turning the tide on gray hair, from systemic supplements using catalase to instant-coverage dye shampoos, so you can find the right best anti gray hair treatment for your specific needs and tolerance for risk.
How To Choose The Best Anti Gray Hair Treatment
The “anti-gray” market splits into two distinct camps: systemic supplements that aim to reverse the chemical cause of graying, and topical products that cover or dye the hair shaft. Your choice depends entirely on your goal — do you want to address the root cause or simply hide the evidence?
Catalase Enzyme Content
Catalase is the most scientifically backed ingredient for reversing gray hair. It neutralizes hydrogen peroxide buildup in the follicle, which is the primary driver of graying. A high-quality supplement will contain at least 2,000–3,000 mg of catalase per serving. Without a clinically meaningful dose, any oral treatment is essentially a multivitamin with little chance of effect.
Delivery Method: Systemic vs. Topical
Topical treatments like dye shampoos or salon ampoules offer immediate cosmetic results — the gray disappears in 10–15 minutes. They are ideal for a quick fix and can last several weeks. Oral supplements require 3–9 months of consistent use and may only prevent new grays from appearing rather than reversing existing ones. Understanding this trade-off is critical before spending any money.
Ingredient Purity and Safety
Avoid products with parabens, ammonia, or harsh chemical dyes if you have a sensitive scalp. For supplements, look for GMP-certified manufacturing and third-party testing. Herbal ingredients like Polygonum multiflorum (Fo-Ti), ginseng, and biotin can support overall hair health, but they are not a substitute for catalase when it comes to reversing the graying process itself.

In‑Depth Reviews
1. Gray Hair Rescind with Catalase
This is the supplement that the most serious reviewers settle on — the one with the highest catalase dose among our picks and a formula built by a team of doctors. Each serving delivers a substantial amount of catalase, the enzyme that breaks down hydrogen peroxide in the follicle, alongside saw palmetto, zinc, and a full B-complex. It is also GMP-certified and third-party tested for purity.
The clinical rationale here is solid: without enough catalase, peroxide builds up and bleaches the hair shaft from within. Users who stuck with it for 6–9 months reported visible slowing of new gray growth. It won’t work overnight, but it is the only product on our list with the ingredient profile and manufacturing standards that align with the actual science of graying.
Two capsules per day with meals is the protocol. Given that it has 20 active ingredients, including Pantothenic Acid and Folic Acid, it also supports skin and nail health as a secondary benefit. If you are serious about reversing gray hair at the source, this is the most credible option available.
Why it’s great
- High-dose catalase matches the biological cause of graying
- GMP-certified and third-party tested
- Includes hair-supporting vitamins and saw palmetto
Good to know
- Requires 3–9 months of consistent use for visible results
- Premium-tier price for a 60-capsule supply
2. Anti-Gray Hair 7050 (2 Bottles)
This is the traditional herbal-plus-vitamin approach to fighting gray hair. The formula leans heavily on B vitamins (Biotin, Niacin, B6) and mineral cofactors combined with plant extracts. User reviews are mixed — some saw results over 6+ months, while others experienced no change. The formulation does not specify a catalase dose, which makes it more of a general hair-support supplement than a targeted reversal agent.
Where this product earns its spot is as an affordable two-bottle pack for those who want to try the systemic route without a big investment. Several verified buyers noted that it seemed to prevent new grays from appearing, even if it didn’t reverse existing ones. That is a realistic expectation for a formula that prioritizes nutrition over enzymatic intervention.
The manufacturer MÄRITZMAYER LABORATORIES has a long track record in this niche, and the product is not discontinued. If you want to test whether a supplement approach works for your body without committing to a premium catalase product, this is a reasonable entry point.
Why it’s great
- Budget-friendly two-bottle pack for trial
- Contains essential B vitamins and herbal extracts
- Long-standing product with loyal users
Good to know
- No clinically meaningful catalase dose
- Results are inconsistent across user reports
3. Salerm Gray Cover Hair Treatment Serum
Salerm takes a completely different approach — instead of supplements or dye shampoos, it is a professional-grade ampoule that you mix into any oxidative hair dye. The formula uses a specific combination of electrolytes and surfactants to open up the hair cuticle, allowing color molecules to penetrate deeper into resistant white or gray hairs.
This is a niche product best suited for people who already dye their hair at home or in a salon but struggle with coverage on stubborn gray patches. The ampoule also neutralizes the typical ammonia smell of oxidative dyes, which is a welcome side benefit. Each box contains 12 single-use ampoules, enough for 12 full dye sessions.
It is not a standalone treatment — you need to supply your own dye. But for those who have given up on covering every last gray strand with standard box dye, this booster can make a measurable difference in how uniformly the color takes to the most resistant white hairs.
Why it’s great
- Enhances dye penetration into stubborn white hairs
- Neutralizes unpleasant chemical smells during coloring
- Professional-grade formula with electrolytes
Good to know
- Requires a separate hair dye to work
- Only 12 applications per box
4. Fedulili Instant Natural Brown Hair Color Shampoo
This is the heavy-duty dye shampoo of the group: a 500 mL bottle designed to cover gray hair in 10–15 minutes with a natural brown shade. The formula relies on plant extracts like Polygonum multiflorum, ginseng, and black sesame rather than ammonia. It deposits color onto the hair shaft surface, which makes it safer for sensitive scalps than traditional permanent dyes.
The instructions are straightforward — apply it to dry hair (not wet), work it in like a regular shampoo, lather, and rinse after a few minutes. Users report the color lasts roughly a month, and the big bottle provides around 10 full applications. That is a solid value for someone who wants salon-level coverage at home without mixing chemicals.
The trade-off is that it only comes in brown — it is not suitable for black or blonde coverage. It also requires a patch test before first use, as with any topical dye. If you need a quick, reliable way to cover grays and you are comfortable with a brown shade, this is an excellent cosmetic solution.
Why it’s great
- 100% coverage in 10–15 minutes
- Plant-based formula without ammonia
- Large 500 mL bottle lasts for multiple applications
Good to know
- Only available in brown shades
- Requires a skin allergy test before use
5. SHIHUANUO Black Hair Dye Shampoo 3 in 1
The SHIHUANuo is the closest competitor to the Fedulili shampoo, but in black rather than brown. It is a 3-in-1 formula combining hair dye, shampoo, and conditioner into one product, with a herbal ingredient list including Ganoderma lucidum and ginseng extract. The manufacturer claims coverage lasts over 3 weeks per application.
It is worth noting that this product requires use on dry hair for best results, similar to the Fedulili option. The included herbal extracts are aimed at nourishing the hair shaft while dying it, which is a nice bonus over standard chemical dyes. The 520 mL bottle offers a comparable number of applications to the Fedulili option.
User reports suggest that the black shade is intense and can be messy if not applied carefully. It is a solid entry-level option for anyone with dark hair who wants to cover grays with a single inexpensive product. Just be prepared to do a patch test and wear gloves during the first few uses.
Why it’s great
- Ammonia-free herbal formula for sensitive scalps
- 3-in-1 (dye, shampoo, conditioner) simplifies routine
- Large 520 mL capacity for multiple uses
Good to know
- Works best on dry hair, not compatible with wet application
- Black shade may be too intense for some hair colors
