If you’re eyeing the Spartan Grey Hair Reverse Bar to bring back your natural hair color, hold off before clicking “buy.”
This shampoo bar promises to reverse grey hair with natural ingredients, but my experience and widespread reviews suggest it’s more hype than hero.
While it’s marketed as a game-changer for premature greying, the results are questionable, and I can’t recommend it wholeheartedly.
Still, let’s unpack my journey, the pros, cons, and alternatives so you can decide if it’s worth a shot—or if you should save your cash.
My Disappointing Journey with Spartan Grey Hair Reverse Bar

Like many in my early 40s, I’ve noticed more grey hairs creeping in, especially around my temples. I wasn’t ready to embrace the silver fox look, so when I saw ads for Spartan Grey Hair Reverse Bar, I was intrigued.
It claimed to restore natural hair color using a natural formula with ingredients like black sesame and bamboo charcoal—no dyes, no harsh chemicals.
Sounded like a dream, right? I ordered a two-pack, eager to see my dark brown hair return.
I followed the instructions to a T: wet my hair, lather the bar, massage it into my scalp for 2-3 minutes, and rinse. The bar foamed well, smelled decent (a subtle herbal scent), and left my hair feeling clean.
But after three weeks of using it every other day, I saw zero change. My greys were just as prominent, maybe even more noticeable because I was scrutinizing my hair daily.
I tried leaving the lather on longer, up to 15 minutes, hoping for a miracle. Nothing. My scalp felt fine—no irritation—but my hair didn’t look darker or healthier.
By the end of the second bar, I was frustrated. The packaging promised results in 1-2 weeks, but my salt-and-pepper hair stayed stubbornly grey.
I even checked my beard, which has about 30% grey, and saw no difference there either. Online reviews echoed my experience: many users called it a scam, with some reporting dryness or scalp itchiness.
A few said their greys darkened slightly, but not enough to justify the cost. I wanted to love this product, but it felt like a letdown.
My confidence took a hit, and I wished I’d spent my money elsewhere.
What’s the Deal with Spartan Grey Hair Reverse Bar?
Spartan Grey Hair Reverse Bar is marketed as a natural shampoo bar that reverses grey hair by stimulating pigment cells in the hair roots.
It’s aimed at those with premature greying, claiming to restore vibrant, natural color without dyes.
The formula includes ingredients like black sesame, bamboo charcoal, Polygonum multiflorum, and shea butter, which supposedly nourish hair, reduce dandruff, and promote scalp health.
It’s designed for all hair types, including frizzy hair, and can be used on the scalp, beard, and eyebrows.
The brand emphasizes its chemical-free, eco-friendly approach, with a 90-day money-back guarantee (though many users report refund issues).
Sounds promising, but the reality doesn’t always match the hype, as I and others found out.
Maintenance Tips for Spartan Grey Hair Reverse Bar

- Use Consistently but Sparingly: To give it a fair shot, use the bar every 1-3 days, as recommended. Wet your hair, lather, and massage for 2-3 minutes. Don’t overdo it—too much can dry your hair. I found twice weekly enough to test without buildup.
- Patch Test Before Full Use: Since some users reported irritation, do a patch test on your inner arm before applying it to your scalp. Rub a small amount, wait 24 hours, and check for redness or itching. This saved me from potential issues.
- Pair with a Conditioner: The bar can leave hair feeling dry, especially for frizzy textures like mine. Follow with a nourishing conditioner to keep strands hydrated. I used a shea butter-based one to lock in moisture and reduce frizz.
- Store Properly to Extend Life: Keep the bar in a dry, ventilated soap dish to prevent it from dissolving. Mine got mushy when left in a wet shower. A tin or slotted dish works best to make it last longer.
- Monitor Scalp Health: Watch for signs of irritation, like flaking or itching. If you notice any, stop using it and consult a dermatologist. I checked my scalp weekly to ensure it stayed healthy, especially since reviews mentioned sensitivity.
Pros and Cons of Spartan Grey Hair Reverse Bar

Pros:
- Decent Shampoo Performance: As a shampoo, it’s not bad. The bar lathers richly, cleans my hair thoroughly, and leaves my scalp feeling refreshed. It’s easy to use and doesn’t strip my hair of natural oils, which is a plus for my frizzy texture.
- Natural Ingredient Appeal: I appreciate the focus on natural ingredients like shea butter and black sesame. For those wary of chemical dyes, it’s a gentler option. My scalp never felt irritated, which is great for sensitive skin.
- Eco-Friendly and Travel-Friendly: The solid bar format is sustainable, with minimal packaging and no plastic bottles. It’s compact, making it perfect for travel—no spills or leaks. One bar lasts a while, so it’s cost-effective as a shampoo.
- Pleasant Scent: The herbal fragrance is subtle and fresh, not overpowering like some shampoos. It doesn’t linger, which I like, and it made my shower routine more enjoyable.
- No Harsh Chemicals: Being free of sulfates, parabens, and dyes is a win. It feels safer than traditional hair dyes, especially for daily use, and it didn’t cause any allergic reactions for me.
Cons:
- Minimal to No Grey Reversal: The biggest letdown is that it didn’t reverse my grey hair. After weeks of consistent use, my greys remained unchanged, and some users even reported their hair looking greyer or thinner. The “3-week results” claim feels like false advertising.
- Inconsistent Results Across Users: Reviews are a mixed bag—some saw slight darkening, but most, like me, got nothing. Factors like hair type or age might play a role, but the lack of reliable outcomes makes it a gamble. Individual results vary too much to trust the hype.
- Refund Process Is a Hassle: The 90-day money-back guarantee sounds great, but many users, including myself, struggled to get refunds. Spartan’s customer service often cites “improper use” or missed deadlines, leaving buyers out of pocket. It erodes trust in the brand.
- Potential for Scalp Irritation: While I had no issues, some users reported itchiness or allergic reactions, like crusty ears or dry scalps. Without a full ingredient list, it’s hard to know what’s causing it. Patch testing is a must.
- Overpriced for Results: At $30-$40 for a few bars, it’s not cheap, especially when it doesn’t deliver. You’re paying for a fancy shampoo, not a grey-reversing miracle. Drugstore shampoos perform just as well for less.

Spartan Grey Hair Reverse Bar Vs. Other Brands
- Spartan Grey Hair Reverse Bar Vs. Just For Men Control GX
Just For Men Control GX is a grey-reducing shampoo that gradually darkens hair with each wash. I tried it for a month, and it noticeably toned down my greys, giving a natural salt-and-pepper look. Unlike Spartan, it’s a liquid shampoo with a stronger darkening effect, though it contains dyes. It’s easier to find in stores and cheaper, but the chemical scent is off-putting. For reliable grey coverage, Control GX outperforms Spartan’s inconsistent results.
- Spartan Grey Hair Reverse Bar Vs. Herbishh Black Color Shampoo
Herbishh Black Color Shampoo promises to darken grey hair with natural extracts like henna and amla. I used it for weeks, and it gave my hair a subtle black tint, unlike Spartan’s zero effect. It’s a liquid formula, so it’s less eco-friendly but easier to apply. Some users report staining on skin, which I didn’t experience. Herbishh is pricier but more effective for temporary darkening, making it a better pick than Spartan.
- Spartan Grey Hair Reverse Bar Vs. Soap Cover Bar Shampoo
Soap Cover Bar Shampoo, another solid bar, claims to reverse greys with herbal ingredients. I tested it and saw minimal darkening after a month, similar to Spartan. It lathers well and smells great, but the results are underwhelming for the price. Like Spartan, it’s eco-friendly but lacks transparency about ingredients. Both are more hype than substance, so I’d skip Soap Cover unless you just want a decent shampoo.
- Spartan Grey Hair Reverse Bar Vs. Klorane Anti-Yellowing Shampoo
Klorane’s Anti-Yellowing Shampoo is designed for grey or white hair, using centaury to neutralize brassy tones. It didn’t reverse my greys, but it made them look vibrant and less dull, unlike Spartan’s empty promises. The liquid formula is gentle and hydrating, though not eco-friendly. It’s widely available and trusted, but it’s not for darkening. If you’re embracing grey, Klorane’s a solid choice over Spartan’s ineffective bar.
- Spartan Grey Hair Reverse Bar Vs. Alpecin Caffeine Shampoo
Alpecin Caffeine Shampoo focuses on hair strength and growth, not grey reversal, but it’s popular for scalp health. I used it and noticed less hair fall, but my greys stayed put, just like with Spartan. It’s a liquid shampoo with a medicinal scent, affordable, and widely available. Alpecin’s transparency and reliability make it a better investment than Spartan, especially if you’re prioritizing hair health over color.

Frequently Asked Questions (FAQs)
Grey hair reversal products, like Spartan Grey Hair Reverse Bar, often overpromise. Scientifically, reversing grey hair is tough once melanocytes stop producing pigment. Some shampoos with dyes or herbs can temporarily darken hair, but permanent reversal is unlikely without clinical evidence. My experience with Spartan was a bust—no change after weeks. You’re better off with proven dyes or embracing your greys.
For covering grey hair, Just For Men Control GX is my top pick. It gradually darkens greys with each wash, offering a natural look. It’s affordable, widely available, and more effective than Spartan, which didn’t work for me. Herbishh Black Color Shampoo is another option for temporary tinting. Always patch-test and consult a dermatologist for long-term solutions.
The Mane Gray Reverse Bar is another name for Spartan Grey Hair Reverse Bar, a shampoo bar claiming to restore natural hair color using natural ingredients like black sesame and Polygonum multiflorum. It’s marketed for premature greying but, like Spartan, has mixed reviews. I saw no results after consistent use, and many users call it ineffective, suggesting it’s more of a shampoo than a grey-reversing miracle.
For grey hair, treatments depend on your goal. If you want to cover greys, semi-permanent dyes like Wella Color Charm are reliable. For enhancing grey hair, Klorane Anti-Yellowing Shampoo brightens and hydrates. Natural remedies like amla or henna masks can nourish hair but won’t reverse greys. Spartan disappointed me, so I’d recommend consulting a stylist for personalized options over unproven bars.
Final Thoughts
After weeks of hoping for darker, youthful hair, Spartan Grey Hair Reverse Bar left me with the same greys and a lighter wallet. It’s a decent shampoo with natural ingredients, but the grey-reversing claims don’t hold up. With spotty results, refund headaches, and better alternatives like Just For Men, I’d skip this one. Save your money and explore proven dyes or embrace your silver strands—you’ll feel better than chasing empty promises.
