Description
What is NeoGenesis Hair Thickening Serum?
NeoGenesis Hair Thickening Serum is the NeoGenesis scalp serum, dermatologist recommended and powered by 60% S3RM exosome technology: conditioned media from three stem cell types, human dermal papilla progenitor cells, adipose mesenchymal stem cells and fibroblasts, with EGCG-rich green tea and red clover extracts and a botanical antioxidant complex of Larix europaea, Santalum acuminatum, Citrus glauca and Acacia victoriae. Apply 2 to 3 drops to the areas of the scalp you want to support and massage lightly, twice daily for the first 30 days and daily thereafter. Available at SkinCrew in 30 mL ($249).
Sourced direct from NeoGenesis: guaranteed authentic, batch-fresh, fast US shipping.
The problem
Hair that looks thin, sparse or flat usually starts at the scalp, and most thickening products work on the hair shaft instead: volumizing sprays that wash out, or heavy oils that weigh fine hair down and leave residue. A dry, flaking or irritated-feeling scalp is rarely addressed at all.
60% S3RM for a balanced scalp and thicker, fuller-looking hair.
Hair Thickening Serum applies the NeoGenesis secretome approach to the scalp environment. S3RM supports a well-functioning scalp and the look of hair density, helping reduce the appearance of shedding while enhancing body and shine, and the green tea, red clover and botanical layer adds antioxidant and nutrient support. The lightweight, water-based texture leaves no residue, so you style exactly as usual. NeoGenesis pairs it with NeoBrow and NeoLash, which use the same technology.

NeoGenesis Hair Thickening Serum: strengthen and nourish with 60% S3RM
NeoGenesis Hair Thickening Serum takes the NeoGenesis secretome approach to the scalp. It is powered by 60% S3RM exosome technology, conditioned media from three stem cell types: human dermal papilla progenitor cells, adipose mesenchymal stem cells and fibroblasts. NeoGenesis positions it to support a well-functioning scalp environment and improve the look of hair density, helping reduce the appearance of shedding while enhancing body, shine and hair that looks thicker, fuller and at its best.
Around the S3RM sits a botanical layer: EGCG-rich green tea and red clover extracts that help offset the effects of DHT-related stress associated with visible thinning and shedding, plus Larix europaea, Santalum acuminatum, Citrus glauca and Acacia victoriae for antioxidant and nutrient support. It is dermatologist recommended, water-light and residue-free. Apply 2 to 3 drops to the scalp, massage lightly and style as usual, twice daily for the first 30 days and daily after that. Available at SkinCrew, an Authorized NeoGenesis US Retailer, with fast US shipping.

Why Hair Thickening Serum Stands Out
- What S3RM means. S3RM is the NeoGenesis exosome technology for hair, brows and lashes: the released molecules from three stem cell types, including scalp-native dermal papilla progenitor cells alongside the adipose and fibroblast sources used in the skin serums.
- Green tea and red clover. EGCG-rich green tea polyphenols and Trifolium pratense help offset the effects of DHT-related stress associated with visible thinning and shedding while giving the scalp antioxidant support.
- Botanical antioxidant complex. Larix europaea, Santalum acuminatum, Citrus glauca and Acacia victoriae provide antioxidant and nutrient support to help protect follicles from oxidative stress and support scalp and hair vitality.
- Zinc and glycine. Zinc chloride and glycine round out a water-based, hydroxyethylcellulose-gelled formula that absorbs into the scalp without weighing hair down.
| Feature | Hair Thickening Serum | Growth factor or peptide scalp serums | Caffeine or biotin serums |

| Scalp support | Calms the look of dryness, flaking and irritation with botanical antioxidants | Rarely addressed | Often drying alcohol bases |
| Botanicals | Green tea, red clover, Larix, Santalum, Citrus glauca and Acacia victoriae | Varies | Minimal |
| Finish | Water-light, residue-free, style as usual | Varies | Often greasy or tacky |

The Science Behind S3RM
S2RM stands for stem cell released molecules. NeoGenesis describes it as the complete secretome of human fibroblast and adipose mesenchymal stem cells: the growth factors, peptides, cytokines, antioxidants and extracellular vesicles, including exosomes, that these cells naturally release. The products contain conditioned media, the molecules the cells secrete, and no live cells. For hair, brow and lash, NeoGenesis uses S3RM, which adds the secretome of dermal papilla progenitor cells to the same base.
The brand names Dr. Raja Sivamani, a dermatologist, as Head of its Scientific Medical Advisory Board, and describes its products as dermatologist recommended. NeoGenesis states that S2RM is patented and that the technology is made for all skin types.
NeoGenesis also publishes research on its product pages under titles such as the ones below. We quote these as brand statements rather than as SkinCrew claims.

- Rescue of Degenerating Cells Using S2RM

NeoGenesis Hair Thickening Serum FAQ
What is the best hair thickening serum?
A good hair thickening serum improves the look of thickness and density while supporting a well-functioning scalp. NeoGenesis Hair Thickening Serum combines conditioned media from skin and scalp cell types (60% S3RM) with botanical extracts to help provide a balanced scalp environment for hair that looks thicker and fuller.
Does NeoGenesis Hair Thickening Serum work on thin-looking hair?
It is designed for hair that looks thin or sparse. The serum helps improve the appearance of fullness and density, and with continued use NeoGenesis says hair appears thicker, more voluminous and at its best. It makes no medical claims and is a cosmetic scalp serum.
How does a hair thickening serum work?
By supporting the scalp environment and improving the appearance of hair density and fullness. Hair Thickening Serum combines S3RM conditioned media with plant extracts such as green tea and red clover to nourish the scalp and support fuller-looking hair.
What makes this different from other hair serums?
Most hair serums rely on caffeine, biotin or a single peptide. NeoGenesis uses scalp-native S3RM exosome technology from three stem cell types to support a balanced scalp environment, calm the look of irritation and improve the appearance of hair density for fuller, thicker-looking hair.
How long should I use it before I see a difference?
NeoGenesis recommends twice-daily application for the first 30 days, then once daily. Results depend on the person and on consistency, so treat it as a daily routine rather than a quick fix.
Will it make my hair greasy or affect styling?
No. It is a water-based, lightweight serum applied directly to the scalp, not the lengths. Apply 2 to 3 drops, massage lightly and style as usual.
Are there before and after photos for Hair Thickening Serum?
Yes. NeoGenesis publishes before and after case photos from its professional partners, and a selection that used Hair Thickening Serum is shown on this page with every product in the routine listed in the caption. Individual results vary.
Is there a video on how to use Hair Thickening Serum?
Yes. The NeoGenesis product video on this page walks through Hair Thickening Serum, what is in it and how to apply it, and the science video explains the stem cell released molecules behind the line.
Is SkinCrew an authorized NeoGenesis retailer in the US?
Yes. SkinCrew is an Authorized NeoGenesis US Retailer and sources every unit directly from NeoGenesis, so Hair Thickening Serum arrives fresh, authentic and covered by the brand guarantee, with fast US shipping.
