How long until I see results?

Most people notice less shedding within 2-3 weeks. Baby hairs and visible regrowth typically appear around week 4-8. Full thickness and density improvement happens around 8-12 weeks with consistent daily use.

Will this work if I've been losing hair for years? Yes. Your follicles aren't dead, they're dormant.

Yes. Your follicles aren't dead, they're dormant. As long as the follicle is still there, the 3-2-3 activation sequence can wake it back up. We've seen regrowth in people who've been thinning for 5+ years.


How is this different from minoxidil? 

Minoxidil forces follicles to grow but doesn't block DHT (what kills them in the first place). We block DHT while feeding follicles what they need. That's why results stick and you don't have the rebound shedding when you stop.


Will it make my scalp itchy or cause breakouts? 

Our formula is designed to be gentle, but everyone's skin is different. If you have sensitive skin, test on a small area first. The serum is free of parabens, sulfates, and phthalates. If irritation occurs, discontinue use.

I was noticing more thinning around my hairline and part, and it really affected my confidence. This roll-on made it so easy to apply right where I needed it. After staying consistent, my scalp feels healthier and my hair looks fuller overall.

I’ve tried so many hair products that were messy or hard to use consistently. I love that this is a roll-on — no dripping, no greasy feel. My hair shedding looks reduced and I’m starting to notice little baby hairs along my hairline.

I assumed thinning hair was just something I had to accept. This serum made me realize how important scalp care is. My hair feels stronger at the roots and looks healthier without feeling oily or weighed down.

I used to avoid scalp products because they felt heavy or greasy. This one absorbs quickly and fits into my daily routine. My hair looks thicker at the crown and my scalp feels balanced and nourished.

The Reason Your Hair Keeps Falling Out Has Nothing to Do With Your Shampoo.

You have probably tried more than one product by now. You have probably stood in the shower and watched your hair fall and felt that quiet fear that it was never going to stop. That feeling is real because you were never given the right answer. Most products only touch the outside of your hair. They were never made to go deep enough to fix what is actually broken. The PDRN Ampoule Serum was built differently. It goes straight to the root where the problem starts, feeds what your follicles have been missing, and gives your hair what it needs to grow back stronger from the inside out.

This Is What Happens to Thinning Hair When You Go Straight to the Root and Fix It From the Inside.

When the root gets what it has been missing the hair has no choice but to respond. That is not a promise. That is just how the body works. The thinning you have been seeing is not permanent. It is the result of a root that has been starving for the right things for a long time. What makes this different is that our PDRN complex is the only one of its kind clinically shown to reactivate dormant follicles in as little as 21 days. In a third party study 94 percent of participants reported a visible reduction in thinning within their first month. What you are looking at in this photo is not special. It is just what hair does when the root is no longer being ignored.

FAQ

What if I don't see results? +
 Hair regrowth takes time. Give it the full 8-12 weeks of consistent twice-daily use. If you're not seeing reduced shedding by week 3-4, you may need to check with a dermatologist as there could be an underlying medical issue.
Will my hair fall out again if I stop using it?  +
Unlike minoxidil, you're not forcing growth, you're fixing the root cause. Many people maintain results after stopping, though continued use optimizes ongoing growth. Think of it like working out. You keep the muscle but maintenance helps.
Is there a subscription or can I just buy one bottle?  +
You can purchase one-time or subscribe for a discount. If you do subscribe, you can pause, skip, or cancel anytime from your account. No phone calls needed. You're in complete control.
Can I use this if I'm pregnant or breastfeeding? +
We recommend consulting with your doctor first. While our formula uses natural actives like rosemary, redensyl, and anagain, hormonal changes during pregnancy can affect hair differently. Your healthcare provider can advise what's safe for your situation.
Will it work on completely bald areas or just thinning spots?  +
It works best on thinning areas where follicles still exist but are dormant. If an area has been completely bald for 5+ years, the follicles may be permanently closed. However, many people see regrowth in areas they thought were beyond repair. The only way to know is to try.
