South Moon Polygonum Multiflorum Serum Nourishing 100ml
Sometimes the old ways work best. This South Moon formula leans on traditional botanical ingredients that’ve been used for centuries.
It’s built around polygonum, which is one of those ingredients that actually has research behind it.
What it does: nourishing. That’s the main thing, and it does it well.
Comes in a 100ml size, which should last you a good while depending on how often you use it.
What Makes This One Different
- Polygonum — the active ingredients doing the heavy lifting
- Nourishing — the specific concerns this targets
- South Moon — a brand that’s been in the hair care space for a while
- 100ml — decent size for the price
- All hair types — works on straight, wavy, curly, coily, color-treated, you name it
How to Use It
Here’s how to use it: put a few drops on your fingertips, massage into the scalp where you need it most, and let it absorb. No rinsing needed. Do this consistently — once or twice a day — and give it at least 4-6 weeks before judging results.
The Honest Truth
Let’s be real — no single product is magic. But if you use this consistently and pair it with a decent overall routine, you should notice a difference within a month or so.

After postpartum hair loss wrecked my confidence, this product helped me feel like myself again. I use it regularly and my hair has been responding well. I specifically wanted something with glycerin because I’d read about its benefits for hair health, and this delivers. I’m seeing real density improvement at my crown where my scalp used to show through. My dry, brittle ends have transformed into something that actually feels soft and hydrated. The key with any hair care product is consistency – I made it part of my daily routine and stuck with it for 9 weeks before judging the results. This is the real deal – not another overhyped product.

Worth every penny. moisture within a month of daily use.
Grace Clark (verified owner) –
My partner noticed the difference before I even said anything about using a new product. I’ve been using it for about two months now and I’m happy with the progress. The hydration lasts for days between washes instead of evaporating by day two. This is the real deal – not another overhyped product.
Adrian Scott (verified owner) –
I noticed changes faster than I expected – within two weeks my hair felt different. I use it regularly and my hair has been responding well. The regrowth along my temples is visible enough that friends have asked what I’m using. Do yourself a favor and get this.
Noah Torres (verified owner) –
This has earned a permanent spot in my hair care routine. Can’t imagine being without it now. I use it as directed and the results have been steady. The elasticity is back – my hair bends without breaking. I’ve already repurchased and will keep this in my routine indefinitely.
Ellie Williams (verified owner) –
It’s not bad, it’s just not particularly impressive either. Middle of the road for me. I incorporated it into my morning routine and it’s become a habit. The glycerin content was why I bought this, but it doesn’t seem concentrated enough to make a real difference. The relief is temporary – my scalp issues return within hours. My hair felt moisturized initially but the effect didn’t last. I’ve been using it for 7 weeks now and while the results aren’t dramatic, there is some progress. Average product, average results. That’s about all there is to say.
Alexander Wilson (verified owner) –
Best I’ve tried for scalp. Noticed changes in week two.
Amelia Thompson (verified owner) –
I’m in my 40s and my hair has been thinning steadily – this gave me hope again. I use it as directed and the results have been steady. I specifically wanted something with glycerin because I’d read about its benefits for hair health, and this delivers. My hair doesn’t feel like straw anymore – it’s genuinely moisturized from root to tip. My hair doesn’t snap off when I brush it anymore – the breakage is practically gone. It took about 4 weeks of consistent use to really see the difference, so don’t give up if you don’t notice changes in the first few days. Honestly the best hair product purchase I’ve made this year.
Liam Lopez (verified owner) –
My hair feels thicker and the shedding stopped. The glycerin is the real deal.
Lillian White (verified owner) –
I think this might work for some people but it hasn’t been great for my specific hair type. I use it daily as part of my hair care routine. The glycerin content was why I bought this, but it doesn’t seem concentrated enough to make a real difference. The moisture lasts about a day then my hair is back to being dry. The relief is temporary – my scalp issues return within hours. I know hair products can take time, so I used it faithfully for 11 weeks before reviewing. Three stars because it technically does something, just not enough.
Theodore Thomas (verified owner) –
I was ready to see a dermatologist about my hair loss but this has been working so well I haven’t needed to. I incorporated it into my morning routine and it’s become a habit. My hair doesn’t snap off when I brush it anymore – the breakage is practically gone. Can’t recommend this enough for anyone struggling with their hair.
Evelyn Anderson (verified owner) –
My partner noticed the difference before I even said anything about using a new product. I’ve been using it for about two months now and I’m happy with the progress. I can run a comb through my hair without hearing that horrible snapping sound. Honestly the best hair product purchase I’ve made this year.
Sofia Scott (verified owner) –
Actually works. My scalp feels healthier and I see new growth. The glycerin makes a difference.
Jack Anderson (verified owner) –
After postpartum hair loss wrecked my confidence, this product helped me feel like myself again. I use it regularly and my hair has been responding well. My scalp feels balanced – not oily, not dry, just healthy. I only wish I’d started using it sooner.
Jayden Walker (verified owner) –
Worth every penny. strength within a month of daily use.
Daniel Robinson (verified owner) –
I’ve recommended this to three people already because the results speak for themselves. I use it regularly and my hair has been responding well. My scalp itch is completely gone and the flaking has stopped entirely. Do yourself a favor and get this.
Benjamin Anderson (verified owner) –
This has been working for me but I had to figure out the right way to use it. I’ve been using it for about two months now and I’m happy with the progress. Reduced my flaking by about 70% – not completely gone but much better. Good product overall – I’ll keep using it and see if results improve over time.
Zoey Harris (verified owner) –
The difference in my hair texture and growth is something I can actually see and feel. I’ve been using it for about two months now and I’m happy with the progress. My part looks noticeably narrower than it did two months ago. Can’t recommend this enough for anyone struggling with their hair.
Lily Hernandez (verified owner) –
The product itself is decent but I expected more given the claims and the price point. I’ve been using it for about two months now and I’m happy with the progress. I see minimal new growth and the progress is frustratingly slow. I’ll keep looking for something that works better for me.
Evelyn Thomas (verified owner) –
Solid product. Does what it says. Just wish it worked a little faster. I use it as directed and the results have been steady. The moisture is good but it’s a bit heavy for my fine hair – better for thicker hair types. Four stars because it works, just not as fast as I’d hoped.
Jacob Rodriguez (verified owner) –
The difference in my hair texture and growth is something I can actually see and feel. I use it as directed and the results have been steady. My scalp feels balanced – not oily, not dry, just healthy. Do yourself a favor and get this.
Lillian Lewis (verified owner) –
I’m happy with the results so far, though I had to be patient to see them. I use it regularly and my hair has been responding well. Solid hydration but I experience some buildup after about a week of use. I’d recommend it with the caveat that you need to be patient and consistent.
Aria Flores (verified owner) –
This works. glycerin + consistent use = visible results in 3 weeks.
Chloe Davis –

Sarah Torres (verified owner) –
Wish I had found this years ago. My hair feels completely different now. I incorporated it into my morning routine and it’s become a habit. I specifically wanted something with glycerin because I’d read about its benefits for hair health, and this delivers. Even in dry weather, my hair stays hydrated and doesn’t get that crackly texture. The elasticity is back – my hair bends without breaking. It took about 8 weeks of consistent use to really see the difference, so don’t give up if you don’t notice changes in the first few days. Definitely worth the investment for anyone dealing with similar hair concerns.

Amelia Gonzalez (verified owner) –
Wish I had found this years ago. My hair feels completely different now. I use it as directed and the results have been steady. The glycerin is what sets this apart from other products I’ve used – you can feel the quality. The shedding in the shower has reduced dramatically – maybe 80% less hair in the drain. Even in dry weather, my hair stays hydrated and doesn’t get that crackly texture. The key with any hair care product is consistency – I made it part of my daily routine and stuck with it for 9 weeks before judging the results. Do yourself a favor and get this.

Decent product. scalp is noticeable after about 3 weeks of use.
Jayden Young (verified owner) –
After trying what feels like a hundred different products, I finally found something that works for my hair. I use it daily as part of my hair care routine. The moisture balance is perfect – not greasy at the roots, not dry at the ends. I only wish I’d started using it sooner.
Jack Perez (verified owner) –
I’m happy with the results so far, though I had to be patient to see them. I incorporated it into my morning routine and it’s become a habit. There are baby hairs coming in along my temples – progress is real but gradual. Worth trying if you’re looking for something in this category.
Ryan Young –
Average. glycerin is in there but results are underwhelming so far.
