Zenagen vs MONAT: Which One Delivers Better Long-Term Results?

With so many haircare brands promising major transformations (often for big bucks), Zenagen and MONAT might look relatively similar sitting on a shelf next to one another, but their approach is totally different.

One focuses on long-term scalp, follicle, and hair health (Zenagen), while the other leans more into salon shine and surface-level cosmetic improvement (MONAT).

So which one deserves your investment and trust: Zenagen vs. MONAT? That really depends on what you’re hoping to fix, and what kinds of results matter the most to you.

What To Know About Zenagen

Zenagen got its start by addressing hair thinning and shedding; its flagship formula, Revolve, is designed to block DHT, which is a hormone linked to hair loss, and to support regrowth with natural botanicals.

Zenagen offers very few product lines compared to MONAT, but in my opinion, that makes it easier to find (and purchase) exactly what you need. (As I’ll explain later on, it’s easy to get lost in the sea of MONAT products.)

Depending on your specific hair concerns, Zenagen offers:

• Revolve, which is formulated to stop (and reverse) hair thinning
• Evolve, designed specifically for damaged hair
• Eclipse, the color preservation and anti-grey treatment line

Zenagen also provides a range of styling products such as leave-in conditioner, styling foam, dry shampoo, texturing powder, and styling paste.

Zenagen’s approach to hair thinning and overall hair health is focused on plant-based bioactive ingredients rather than harsh chemicals. The natural botanical ingredients are easy to read (and understand when you’re scanning the label), and they include aloe, green tea, alpine willowherb, saw palmetto, grape seed extract, lavender, brahmi, and many others.

Like MONAT, parabens are not used in any of Zenagen’s haircare products. That said, you will find sulfates on the shampoo label, namely ammonium laureth sulfate (ALES) and sodium coco-sulfate (SCS). Compared to traditional harsh sulfates often found in drugstore shampoos, these are a lot milder and create a nice lather without damaging your hair or drying your scalp.

I can attest that after washing with Zenagen shampoo, even after I’ve done an oil treatment, my hair is clean (but not squeaky) after a single wash.

I’ve been using Zenagen’s Evolve line for a while now, which treats damaged and dull hair. It’s no secret that I’ve put my hair through the wringer, as it were, with bleach/highlighting, frequent coloring, and very frequent heat styling. But I noticed a change in my hair even after the first use, and that’s only gotten better and better over the weeks that have passed since.

The one thing that’s a little “unusual” about Zenagen’s shampoo is that after you work it into a lather, you actually leave it in place for about five minutes before rinsing. This is true for all of their product lines (Revolve, Evolve, and Eclipse), actually, and it gives the ingredients active time to work their magic.

Even though my hair is almost down to my waist, I only need a single pump of shampoo to wash my hair, followed by a single pump of conditioner. It took me a little getting used to, since I’d normally have to use a LOT more product with my regular drugstore hair products.

And despite not using the Revolve (anti-thinning) line, I’ve been seeing a lot of baby-hair growth in areas above my temples and along my hairline that I have not had for a very long time:

They’re a little spiky and out of control sometimes since they’re babies, but the fact that they’re growing at all is a lucky bonus I wasn’t expecting.

Zenagen Pros

• Embraces a nutraceutical formula that uses plant-based ingredients (instead of medications or harsh chemicals) to support growth, prevent hair loss, and improve the overall health and feel of your hair.
• The sulfate ingredients in its shampoos are mild and won’t dry out your hair or scalp, and all of Zenagen’s products are paraben-free.
• Carries simplified product lines (and hair care routines) to reverse thinning and thicken hair, undo damage, or preserve color (reducing greys).
• The scent is light and fresh, and pretty unisex (nothing flowery or overly perfume-y).
• You’ll use a lot less product compared to drugstore brands, for both the shampoo and conditioner (so it lasts longer and you aren’t buying as often). 

Zenagen Cons

• Has a fairly high price point compared to drugstore haircare products, but is generally still less expensive than MONAT
• Zenagen products don’t include Minoxidil or other FDA-approved “official” hair-growth drugs

What To Know About MONAT

MONAT’s brand name is a shortened version of Modern Nature, which has a pretty devoted fan base and an equally devoted non-fan base. Their products have a richer, salon-ish vibe that feels like luxurious self-care (although usually with the price tag to match).

In fact, MONAT products are often sold directly by haircare professionals in salons, although anyone can become a market partner and sell products to earn commissions in an MLM structure.

While Zenagen offers a few main product lines and additional styling formulas, MONAT carries a lot of shampoos, conditioners, rinses, sprays, creams, and more. To be honest, if you’re interested in products that achieve specific goals, it can be a little overwhelming to find what you’re looking for.

Like a lot of salon-leaning brands, you’re not just buying shampoo or conditioner, though; you’re buying into a whole system, a whole routine. For some customers, there’s the experience of working with a market partner recommending products based on your hair type. 

MONAT products focus largely on hair softness, hydration, manageability, and shine on the surface level. They’re less about restoration and hair health support, especially compared to Zenagen, favoring cosmetic improvements above anything else.

Which has its place, of course. We all want shiny, healthy-looking hair. But I’m of the mind that healthy hair starts at the root… and glossing over problems doesn’t actually fix them.

MONAT’s formulas are free from parabens and sulfates, and although many “natural” botanicals have a place in their ingredient lists, they tend to be wrapped up within proprietary named blends, like MONASOME, CAPIXYL, or REJUVENIQE. So you won’t necessarily know what that actually means.

And the brand has had its share of controversy over the years, largely around customer experiences and differing opinions about adjustment periods. There is a type of “detox” claimed by some before seeing actual positive changes in the condition of their hair. Some users have also found that they need to rotate MONAT in and out of their routines rather than using it exclusively to minimize scalp dryness or other issues. 

If you’re someone who prefers a much simpler and straightforward hair routine, MONAT might have a much bigger learning curve than you care to invest in. That said, if you want premium-feeling hair care and a deeply-tailored routine, it might be worth trying.

MONAT Pros

• Formulas are luxurious with a high-end salon quality, rich textures, and a focus on hydration and repair.
• Offers a wide product variety that makes it possible to create a very tailored routine (if that’s what you want).
• Works best as part of a multi-step system.
• Products are free from silicones, parabens, and sulfates.

MONAT Cons

• Not very beginner-friendly; it can be overwhelming to find the right formula(s) for your routine.
• Results can vary and might take some trial and error (or even product rotation) to strike the perfect balance.
• The price point is higher than typical salon or retail products.
• Although VIP perks (15% discounts and free shipping) are available, you have to create one initial order of $84 or more, plus a second order of at least that amount, to earn the benefits.

How To Choose Between Zenagen And MONAT

If you’re not sure how to choose between Zenagen and MONAT, here’s a quick guide to help. I’ve broken down what each does best and which type of users they match well.

Zenagen is the better choice if you:

• Are dealing with thinning hair, shedding, or hair loss. (I recommend Zenagen Revolve)
• Need scalp and hair root therapy, or damage reversal with faster results.
• Prefer natural and “cleaner” ingredients you can understand when reading the product label
• Want a simpler routine with fewer products required

MONAT is the better choice if you:

• Prefer a more comprehensive (and involved) hair care system.
• You’re not solely chasing after regrowth, rather deep moisture and conditioning.
• You’re okay with investing more time for the “adjustment period” and/or potentially rotating products in and out.

If hair shedding or thinning is a problem for you, or if you want to treat your hair (and not just clean or style it), I recommend starting with Zenagen. Give it a solid two- or three-month trial to gauge hair density and regrowth in the areas where it’s getting sparse.

If you’re really only after more typical cosmetic hair care, MONAT might be the way to go, but watch for any negative changes in the health of your scalp and hair. Some people go through a “detox” period before noticing results, which are not necessarily immediate.

Final Verdict

After comparing both brands closely, this is the simplest way I can put it: 

MONAT can make your hair look good, but Zenagen helps your hair to be good. 

It gets straight to the root of the problem (literally and figuratively), addressing the things that need to be solved, and not just smoothed over.

Zenagen is less about building a complicated (and expensive!) routine, and more about giving your scalp and hair the targeted care it needs. It provides measurable, positive hair results and not just cosmetic shine, which is why I think it’s the best choice for anyone who’s serious about improving their long-term hair health.
