Stop Fighting a Losing Battle at the Hormonal Level. The Root Cause of Hair Thinning Isn’t Your Testosterone—It’s Asleep Stem Cells.
(And we’ve discovered how to wake them up.)
If you’re like most forward-thinking guys, you’ve been told the story that your hair is doomed by genetics and DHT.
You’ve been offered two choices:
The “Big Pharma” route: Lifelong, systemic drugs with a list of side effects you’d rather not think about.
The “Hope-in-a-Bottle” route: Worthless, overpriced shampoos that promise “hair growth” but deliver little more than foam and fragrance.
Both are flawed. They’re waging the wrong war.
They’re trying to manipulate your hormones, a complex and delicate system, when the real problem is much simpler: The stem cells in your scalp, responsible for generating thick, healthy hair, have gone dormant.
They haven’t died. They’ve just fallen asleep. And every day you wait, more of them enter this dormant state, making reversal harder.
My name is Dr. Dave Woynarowski. As an anti-aging physician, I’ve spent my career helping high-performers optimize their biology. And like you, I’m not interested in “acceptable decline.” I’m interested in solutions.
For years, I fought my own battle with hair thinning. I tried everything from early-access minoxidil to high-dose fish oil. They were temporary fixes—like patching a leaking dam with chewing gum.
The real breakthrough came not from fighting symptoms, but from going to the source. Working with my colleagues in stem cell research, we stopped asking, “How do we block hair-killing hormones?” and started asking, “How do we reactivate the ‘hair-making’ machinery that’s already there?”
The answer is Stem Stim.
This is not another shampoo. It is a clinical-grade, stem cell-derived liposomal serum.
Think of it like a biological wake-up call for your scalp.
We don’t use bogus “plant stem cells” or homeopathic micro-doses. Our formula is derived from the same growth factors used in clinical regenerative therapies. These liposomes are protein messengers that signal your dormant hair follicles to get back to work—building thicker, stronger, and more abundant hair.
This isn’t a cover-up. It’s a biological reset.
I saw it myself. Within weeks of developing this formula, I saw more hair—thicker and faster-growing—than I’d had in over two decades. The “chrome dome” I thought was my destiny is no longer on the horizon.
Here’s The Deal:
This isn’t for everyone. This is for the man who understands that proactive, targeted action is the key to longevity and performance. It’s for the guy who would rather invest in a real solution now than pay for a transplant later.
Because the liposomal growth factors are incredibly potent and fragile, we have to produce and handle this serum with extreme care. This makes it more expensive than the useless junk on store shelves.
For those who are serious, we’ve bundled a complete 2-month “Reactivation” supply.
Why 2 months? Because hair growth is a biological process that takes time. Anyone promising instant results is lying to you. You need to commit to the full cycle to see the dramatic change.
Your investment for the 2-Month Reactivation Supply is $349.
And to make this an absolute no-brainer, here is our “Thicker Hair or It’s Free” Guarantee:
Use the entire 2-month supply of Stem Stim as directed. If you don’t look in the mirror and see a noticeable, undeniable improvement in the thickness and fullness of your hair, simply send us an email, and we will refund 100% of your money.
You can even keep the empty bottles.
That’s how confident we are in the power of this formula. The risk is entirely on us.

We believe in transparency. You’re not buying a “hope in a bottle”; you’re investing in a targeted biological tool. Here are the direct answers to the questions you should be asking.
Stem Stim is not a drug. It works on a completely different pathway. Drugs like Minoxidil are vasodilators (they increase blood flow) and drugs like Finasteride attempt to manipulate hormones (blocking DHT).
Stem Stim works at the source. It delivers a concentrated payload of stem cell-derived liposomal growth factors directly to your scalp. Think of these as biological instructions. They signal your dormant, inactive hair follicles to "wake up" and re-enter the anagen (growth) phase. We're not manipulating your systemic hormones; we are reactivating the local growth machinery that's already there.
Growth factors are protein molecules that signal cells to grow, divide, and differentiate. The ones in our serum are specifically those known to communicate with hair follicle stem cells. The "liposomal" part is crucial. A liposome is a microscopic, fat-soluble vesicle that acts like an armored delivery vehicle, protecting the fragile growth factors from degrading and ensuring they penetrate the scalp to reach the follicle. Without this delivery system, the active ingredients would be significantly less effective.
No. The product contains zero live cells. We cultivate human mesenchymal stem cells in a nutrient-rich laboratory media. As they grow, they release a powerful spectrum of growth factors into this media. We then harvest the media, remove the cells, and put the resulting conditioned media through a proprietary process to purify and concentrate these precious growth factors into the final serum. There is no risk of cell rejection or transmissible disease.
The difference is night and day. Those products typically use one of two worthless ingredients:
Plant Stem Cells: Apple or melon stem cells have zero biological relevance to human hair follicles. It is pure marketing fiction.
Micro-doses: Some products might include a vanishingly small amount of real growth factors just so they can put it on the label.
Stem Stim uses clinical-grade, human-derived growth factors at a concentration high enough to elicit a biological response. The cost of our raw ingredients is hundreds of times higher than what's in a typical bottle of shampoo, which is why it works and they don't.
Hair growth is a slow biological process (think how often you get your hair cut, it takes awhile to grow!). Do not expect an overnight miracle.
Weeks 3-4: The first thing most users notice is a significant reduction in hair shedding in the shower or on their brush. This is a sign the follicles are anchoring more strongly.
Weeks 6-8: You should begin to see and feel new vellus hairs (fine, "baby" hairs) at the hairline and in thinning areas. Your existing hair may start to feel thicker at the root.
Months 2-4: This is when the most noticeable results appear, as those new hairs mature and existing hair becomes demonstrably thicker and fuller.
The goal of Stem Stim is to "reboot" your follicles back into a healthy growth cycle. Once you achieve the results you're happy with, you can stop. The results should last for several months. However, the underlying factors that caused the thinning in the first place may still be present. If you notice thinning beginning again after 6-12 months, you can start another "Reactivation Cycle" to maintain your results. It does not create dependency like minoxidil.
You must have realistic expectations. Stem Stim is designed to reactivate dormant or miniaturizing follicles. If an area of your scalp has been slick-bald for many years, it's likely those follicles have died and can no longer be reactivated. This product is most effective for men who are currently experiencing thinning, a receding hairline, or diffuse hair loss, but still have some follicular activity in those areas. The sooner you start, the more you can save and regrow.
Some users have reported that new hairs initially grow in with their original, darker color. This is a potential side effect of reactivating healthier cellular function in the follicle. However, this is not the primary purpose of the product, and we do not guarantee it will reverse gray hair.
This is your proof of potency. The liposomal growth factors are active biological proteins. Like fresh food, they are fragile and will degrade if left at room temperature for extended periods. Refrigeration maintains their structural integrity and ensures you get the full, potent effect for the entire 2-month cycle. Any "stem cell" product that doesn't require careful storage is likely biologically inert.
We only sell a 2-month supply because we are committed to your success. As explained above, it takes at least 6-8 weeks for the biological process to yield visible results. Lucky for you, we put both months into a single bottle! Selling a smaller, single month bottle would be a disservice to you, as you might quit before the magic happens. We would rather have you be fully committed and get the results you paid for.
It's simple. We call it the "Thicker Hair or It's Free" Guarantee. Use the entire 2-month supply as directed. If at the end of 60 days you don't look in the mirror and see a clear, undeniable improvement in the thickness and fullness of your hair, email our support team. We will refund 100% of your purchase price. No loopholes, no questions asked. The risk is 100% on us.

Holy Crap! It actually works!! I’ve been having some MAJOR ISSUES with my receding hairline and crazy widow peaks… I was super skeptical but figured I like all the other products I’ve had from here and it’s a hell of a lot less than going to Bosley… Could not be happier with the decision to give the hair growth treatment a try. It worked!
Patty –
Best part of my day! My hair feels great and I love the smell. It’s like a spa treatment at home. A little goes a long way and my hair feels softer and conditioned. I love it!!

It’s a massive relief to find something that actually works. After years of trying different things and being disappointed, I feel like I can just stick with this and not have to worry about my hair anymore. If you’re on the fence, just try it, you’re future self will thank you. Appreciate you guys making this stuff!
Fredrick –
My girlfriend has always been supportive but honest. Last night she was running her hands through my hair and said it definitely feels thicker than it has in a long time. Unprompted feedback like that is priceless. Great product, good results.
David –
I’ve quit other treatments because they were oily, sticky, and a pain to use. This is the complete opposite. It’s like water, absorbs in a minute. The fact that it’s so easy to use means I actually stick with it, and I saw results after using just about half the bottle.
Alan –
I’m a data guy (literally a data scientist). I took a photo of my hairline the day I started. Took another one at the 8-week mark in the same lighting. The difference is clear—the density is better and it just looks healthier. I can’t argue with the evidence, will keep using.
Mark –
My wife started using a few drops on her thinning part line after seeing my results. My hair feels fuller, and apparently, it’s effective enough that I now have to buy two at a time. It seems to work even better for her, and that’s saying something because it’s been great for me. Thanks Doc!
Sam –
My crown was getting thin enough that I was starting to get self-conscious under office lights. two months in, the area looks much denser. It’s not a miracle cure, but the improvement is undeniable and a huge confidence booster
Thomas –
I hesitated at the price, but then I thought about what I’d spent on foams and supplements over the years. This is the first product where I’ve seen a visible difference. First rate, best thing I’ve bought in a long time.
Michael –
My temples were my biggest insecurity. After about 7-8 weeks, I can see a bunch of new, fine, dark hairs sprouting in that area. They’re small, but it’s the first time I’ve seen actual regrowth from anything.
Scott –
I was skeptical, but my main goal was to stop seeing so much hair in the shower drain. About a month in, the shedding slowed to almost nothing. Now, at the end of the 2-month supply, my hair just feels more solid and anchored. This stuff is the real deal.
Bill R. –
Hair loss runs in my family—my dad was bald by 40, and I was headed down the same road. By my mid-50s, I had a wide, shiny patch up top and a receding front that made me dread photos. I’ve spent thousands over the years trying every trick out there. Nothing changed—until I tried this.
If you’ve accepted that baldness is “just your genetics,” I urge you to give this a try. The results speak for themselves. I had mile results until the third month and then it just took off. I can honestly say I’m a customer for life as long as my new found hair sticks around!
Matt F –
I didn’t say a word to my barber about taking this. I went in for a cut last week and he said “Whatever you’re doing, keep doing it. It feels way thicker on top.” That was all the proof I needed. I’m super excited!
Nick –
I don’t normally write reviews. This product has dramatically changed my life so I felt obligated to help anyone else who felt as helpless as me.
I’ve tried everything over the years—biotin, shampoos, minoxidil, laser combs—you name it. At best, they slowed the loss. At worst, they did nothing. My confidence took a hit every time I caught a glimpse of my thinning crown under harsh bathroom lighting. When I read about Stem Stim, I figured it was just another “too good to be true” product. But the science behind it seemed legit—stem cell activation…That sounded different.
Within three weeks, I started noticing something strange—texture. The baby hairs that had been invisible for years began feeling thicker and stiffer when I ran my hand over my scalp. By the two-month mark, there was no denying it: my hairline had filled in noticeably, and my wife even commented on it. Now, after six months, I look like I did ten years ago. My wife says I seem like my old self again—more confident, energetic, and honestly, happier.
I take this formula every day now, without fail. It feels like it’s reprogramming my biology to grow hair again. If you’re standing in front of the mirror wondering if it’s too late, take it from me—it’s not. This product is the real deal.
