Sirnagen CosmeRNA for Hair Loss: Now Available in the US

See the bottom half of this post for my original discussion on CosmeRNA. The top half are all new updates.

Update: February 27, 2025

CosmeRNA is Finally Available in the US

CosmeRNA from Bioneer (South Korea) is finally being sold in the US on Amazon. The manufacturer is selling a 0.06 fl oz (1.8 ml) quantity for $89. The active ingredients in this unique hair loss cosmetic is listed as SAMiRNA-68.

CosmeRNA Amazon USA
As of 2025, CosmeRNA is finally available for sale in the US on Amazon.

Update: March 21, 2024

CosmeRNA is now available in a lower-cost smaller container of just 1mL. It is priced at €84 (but currently has a 10% off sale offer) and will last for 1-2 months.

On Amazon UK, it is still also sold in the 6mL version, but at a discounted price of £190. It currently has an average rating of 3.4 out of 5 stars based on 34 reviews.

Recently, Bioneer’s CEO Han-Oh Park made a detailed video presentation in English at IMCAS 2024 that is worth watching.

The key active ingredient in CosmeRNA is “SAMI-RNA AR68″ (StearyldisulfidehexylDNA-2-PEG-45/SH-RNA-1). It is designed to selectively inhibit the expression of the androgen receptor (AR) in hair follicle cells.

Update: February 21, 2024

Make sure to check this pdf about CosmeRNA that was sent to me by Bioneer. The company has completed CosmeRNA’s Amazon Europe entry into Italy, Germany, France and Spain. Note that it previously only sold CosmeRNA on the Amazon UK website. In future, they will sell the product in Japan, Australia and Singapore.

Update: July 18, 2023

Bioneer has installed five additional high-capacity synthesizers in order to double the production capacity of patented raw materials for CosmeRNA, the world’s first RNA based hair loss relief cosmetic. Bioneer aims to secure more than 100 million of the world’s 2 billion male and female hair loss sufferers as CosmeRNA customers. Hopefully, the resulting economies of scale will allow a reduction in the product’s price.

Update: June 14, 2023

CosmeRNA is Now on Sale on Amazon

CosmeRNA is now available for sale via the UK Amazon site. It can be shipped and delivered to the US and other countries too. Make sure to review and rate the product if you use it for a few months.

South Korea just keeps on adding groundbreaking companies working on new hair loss treatments. The latest of these is Bioneer’s siRNA based cosmeceutical called CosmeRNA that targets the androgen receptor.

It can supposedly grow 1.3-1.9 hairs/cm per month, which is comparable to finasteride. Make sure to also read my post on how many hairs on a human head?

CosmeRNA was released in Western Europe in May 2023. Note that the top half of this post is all updates.

Update: May 2, 2023

  • CosmeRNA online shop is now open! The price is €300 ($330) per bottle (vial), higher than originally expected. However, per the company’s site, it seems like the frequency of application will be reduced once all the androgen receptors are inhibited. Initially, the treatment is applied topically every two weeks for the first four months. Afterwards, once a month application may be sufficient to maintain the fuller hair.

Besides the key siRNA technology, the other ingredients are listed as follows:

Aqua, Phosphate Buffered Saline, Alcohol, Butylene Glycol, Betaine, Niacinamide, Stearyldisulfidehexyl DNA-2-PED-45/SH-RNA-1, Panthenol, Menthol, Sodium, Biotin, Citric Acid.

— It looks like Bioneer’s CosmeRNA Mall will finally open tomorrow. They describe the product as:

“The world’s first hair loss relief cosmetic based on RNA technology.”

CosmeRNA Release Date Confirmed

Thanks to “Mathis” for the weekly updates. CosmeRNA’s slightly delayed release date is now confirmed for May 2023 per various news articles. Bioneer aims to get 100 million users within 5 years per CEO Park Han-oh. Release of the product in South Korea has been delayed due to some legal issues, although there is a lot of demand in the country.

The below YouTuber managed to contact a Bioneer employee and estimates the cost to be $67 per month. Based on a single $200 priced 6ml bottle lasting for three months, with 1ml recommended usage every two weeks. For comparison, the best laser hair growth devices cost $1000 or more, although the Lasercomb is much cheaper.

February 22, 2023

CosmeRNA related news just keeps coming and seems very encouraging. In the latest article from South Korean media, the company makes some bold claims:

  1. They expect sales of up to 160 billion Won (i.e., $123 million). This is quite extraordinary for a new cosmeceutical hair loss product that will only be sold in one region (Western Europe) for the time being.
  2. They state that “when the shopping mall opens at the end of next month, we will start full-fledged sales for European buyers.” So the product will be on sale by the end of March 2023.
  3. Since siRNA is mainly used for research, very few facilities have mass production capabilities. The scale of siRNA synthesis for most studies is at the mg level. Per this latest news, Bioneer can produce raw materials at a level of 1kg to 1.5kg per month,
  4. There are no major side effects and the product application does not leave any sticky residue.

Note that earlier this month, Bioneer announced that it will even sell on Amazon. And they will be partnering with Ace Biome for marketing and distribution purposes.

Registration on CPNP and SCPN Cosmetic Product Notification Portals

February 2, 2023 — Yet more encouraging news. Bioneer has also completed product registration with Britain’s submit a cosmetic product notification (SCPN) portal. Moreover, in January it participated in “IMCAS World Congress 2023” in France. this was in order to introduce Cosmerna to buyers around the world and to secure a distribution network.

December 26, 2022 — Bioneer announced that it has completed the registration of CosmeRNA on the cosmetic products notification portal (CPNP). The latter is a European cosmetics certification system and means that Bioneer can now distribute CosmeRNA throughout the EU.

CosmeRNA from Sirnagen (Bioneer) Releasing in 2023

This post covers a new topical hair loss product called CosmeRNA, whose website is now live. It is made by siRNAgen (South Korea), a subsidiary of Bioneer (South Korea). I briefly covered this company in the past, but now it deserves its own post.

The reason I am writing this post is due to a great new interview with siRNAgen CEO Dr. June Park. Both these new developments were sent to me by a reader who wishes to remain anonymous. Key quote from Dr. Park (also see her Linkedin):

“The first SAMiRNA product will be available for sale in the first half of 2023. We had an unconventional route to commercialization by developing a hair loss cosmeceutical product. CosmeRNA, named after cosmetic RNA, provided an early validation of our platform’s potential as a topical cosmetic product for androgenetic alopecia (hair loss).”

They will not need to conduct clinical trials since this is a cosmetic product! The actual release date is likely to be in early 2023 per another quote in the same interview. After first being done in South Korea, CosmeRNA’s safety study was repeated in Europe by Dermatest in 2022. Note that SAMiRNA is shelf stable in a solution for a year, so it can be applied topically.

Ms. Park anticipates the product launch to occur some time in early 2023. They will focus on the European market first due to the region’s more streamlined cosmeceutical trial and approval process. Via the Cosmetics Product Notification Portal (CPNP).

Note that I previously briefly covered siRNAgen Therapeutics in my post on OliX Pharmaceuticals. The latter is working on a hair loss cure involving RNA interference (RNAi) via asiRNA (asymmetric small interfering RNA). The aim is to reduce androgen receptor (AR) expression on the scalp.

SAMiRNA, Androgen Receptor and Hair Growth

Like OliX, siRNAgen is also working on reducing AR expression and re-growing hair. However, it is doing so via treatment with self-assembled micelle inhibitory RNA (SAMiRNA) nanoparticle-type siRNA. See their site for more on small interfering RNAs (siRNA).

They published an important study on this in Nature Journal in January 2022. The encouraging title of this paper is worth posting: “Weekly treatment with SAMiRNA targeting the androgen receptor ameliorates androgenetic alopecia.”

The product they use for androgenetic alopecia is a topical called AR68. It is classified as a cosmetic ingredient and will be called Cosmerna-68. In the above mentioned paper, they have before and after photos of a patient that I pasted below. The chart on the right shows the actual percent improvement with AR68 0.5mg/ml treatment versus placebo. They also state the following:

“In the low-dose (0.5 mg/ml) clinical study, AR68 was applied three times per week for 24 weeks, and through quantitative analysis using a phototrichogram, we confirmed increases in total hair counts. In the 24-week long high-dose (5 mg/ml) clinical study, AR68 showed average additional hair growth of 1.3-1.9 hairs/cm2 per month, which is comparable to finasteride. No side effects were observed. Therefore, SAMiRNA targeting AR mRNA is a potential novel topical treatment for AGA.”

0.5 mg/ml AR68 (3x a week) Before and After

5 mg/ml AR68 (1x a week) Before and After

The higher dose AR68 5mg/ml cohort’s before and after photos are here. The researchers claim that these results at 24 weeks are comparable to those from Finasteride. Safety was good in both low-dose and high-dose studies.

Summary

Is this a miracle? Most likely not for most severely balding people people. However, just as with finasteride, some people could see stellar results. And for those who only recently started to go bald, this could be a much needed non-DHT inhibiting product. With few if any side effects.

I am not a big believer in cosmetics, but this latest interview with siRNAgen CEO June Park is encouraging. She comes across as very intelligent and sincere. Note that in Bioneer’s September 2021 presentation, they describe CosmeRNA as a game changer hair loss treatment. It will have no side effect issues such as those seen with Finasteride (Propecia).

Can you Reverse Grey Hair? New Updates.

My original post on a grey hair cure has gotten out of hand due to the constant new updates. I am therefore moving all the most recent grey hair reversal related developments into this post. It is worth reading both posts in their entirety.

Update: April 2025

Targeting the prolactin receptor could restore hair pigmentation per a note on Absci’s website regarding its ABS-201 product. Upon further research, I found a 2006 study that mentions prolactin inducing cessation of pigmentation.

In a podcast with Joe Rogan, the CEO of Colossal Biosciences Ben Lamm mentioned a new company spun out of Harvard that is developing a treatment to reverse grey hair. They deliver melanocyte stem cells and medications via microneedle patches. It is not clear which company he is talking about.

Update: March 2025

Vasoactive intestinal peptide operates as a negative regulator of human hair follicle pigmentation.

Update: February 25, 2024

Hormones and Hair Greying

In a new German study titled “Endocrine Controls of Skin Aging“, one of the subjects covered is hair graying. According to lead author Markus Böhm, hormones may have therapeutic potential to prevent both skin wrinkling and hair greying. The researchers studied pivotal hormones that control skin aging, including insulin-like growth factor 1, growth hormone, estrogens, retinoids and melatonin. They also analyzed additional endocrine players, including α-melanocyte-stimulating hormone, members of the hypothalamic-pituitary-thyroid axis, oxytocin, endocannabinoids (found in CBD products) and peroxisome proliferator-activated receptor modulators.

Update: February 6, 2025

A new Japanese study in mice found that luteolin (an antioxidant found in vegetables) may contribute to the prevention of hair graying. Actual study is here.

Update: February 5, 2025

Phase 3 Clinical Trial for a Grey Hair Repigmentation Product

In a bolt from the blue, a reader sent me a link to a Phase 3 clinical trial from Applied Biology in relation to a grey hair (canities) treatment called CS-001. The 240-person Phase 3 trial will begin on June 15, 2025 and end on June 15 2027. Half the volunteers will be in the placebo group. CS-001 is described as a small molecule that:

“Affects lysosomal storage and transfer of melanin from hair follicle melanocytes.”

In vitro and a small pilot study already demonstrated re-pigmentation of grey hair following CS-001 application. I am not sure if they ever conducted Phase 1 or Phase 2 trials. It is also strange that while Applied Biology was sold in 2022, the company’s name and that of its CEO Dr. Andy Goren are still listed in the above clinical trial page link. Applied Biology developed a widely discussed minoxidil sulfotransferase enzyme booster hair growth product that I covered in detail.

Grey Hair Reversal: Latest Updates

Update: December 12, 2024

In a new Japanese study led by the renowned Junji Fukuda, researchers found that the knockdown of genes associated with melanosome production (Bcl2 and Mitf) and transport (MyoX, PAR2, and Rab11b) significantly increased the number of gray hairs in hair follicle organoids. This new organoid model allows for a better understanding of hair pigmentation, and potential screening of new grey hair reversal drugs.

Update: August 2024

The University of Bradford (UK) and Coegin Pharma (Sweden) partnership will release various peptide based products to target skin and hair pigmentation. The first product to increase skin pigmentation (i.e., self-tanning) will likely come out in 2026.

A new study finds that the bitter taste receptor TAS2R50 is a novel regulator of human scalp hair follicle pigmentation. One of the co-authors is Ralf Paus, and his company Cutaneon holds a patent (see number 7) for TAS2R50 and regulation of pigmentation.

Update: July 30, 2024

Nicotinamide Riboside and Pterostilbene
Liposomal Nicotinamide Riboside and Pterostilbene Supplement for Grey Hair Reversal.

Reader “Andy” just posted an interesting link regarding a patent for a new grey hair treatment that combines Pterostilbene and Nicotinamide.

A popular supplement on Amazon that contains both Pterostilbene and Nicotinamide has one reviewer who said that it helped her friend with grey hair.

Moreover, upon further research, I found the following encouraging 2-year old comment from a Subreddit on supplements:

Can hair greying be prevented?

Update: September 6, 2023

A new South Korean company named YJ Lab is raising funds to start a large-scale clinical trial for its unique melanin restoration technology. The company recently developed a regenerative material that restores the pigment of grey hair. It re-activates damaged melanocytes and removes active oxygen in order to restore hair color. It has already conducted successful internal trials.

Interestingly, YJ Lab is developing a specially made comb equipped with its refillable solution. Consumers can then conveniently apply this melanocyte regeneration material into the scalp.

Update: August 28, 2023

Yet another detailed new study from China covering the reversal of gray hair. The authors summarize melanogenesis and review various existing cases of hair repigmentation. These including monoclonal antibody drugs, tyrosine kinase inhibitors (TKIs), immunomodulators, micro-injury and tumors. They also emphasize further clinical research in developing topical therapies to reverse grey hair.

Update: June 3, 2023

A very detailed new study from China in regards to the genetics of hair greying with age. One of the past sources they mention is the important hair genes study from Adhikari that I covered in 2016.

Update: May 22, 2023

Per a new study from Takahiro Suzuki et al, topically applied Rapamycin could reverse grey hair via mTORC1 inhibition. Rapamycin elevates the production of melanin and pigmentation. I covered rapamycin in my post on autophagy.

Update: April 19, 2023

Cause of Grey Hair may be Stuck Cells

The has been yet another breakthrough on finding the reason behind hair going grey. Scientists from New York University (NYU) found that melanocyte stem cells (McSCs) stop roaming around the follicle and become fixed or “stuck” in limbo as we age. As a result, they fail to mature into fully-fledged melanocytes that give hair its pigment.

The scientists conclude that modulating McSC mobility may represent a new approach for the prevention and even partial reversal of hair greying. The study lead investigator was Dr. Qi Sun and the senior investigator was Dr. Mayumi Ito, who I have mentioned before in this post. I like her quote in Guardian:

“It is the loss of chameleon-like function in melanocyte stem cells that may be responsible for greying and loss of hair colour.”

Update: March 31, 2023

An interesting one-off case of a male patient from Oman who got cyclosporine A induced hair repigmentation in his scalp, moustache and beard hair. Make sure to also read my past post on cyclosporine and hair growth.

Update: December 29, 2022

The Thymus Gland and Reversing Grey Hair

A new article on anti-aging has several items of interest in relation to grey hair reversal. A 72-year-old scientist named Gregory Fahy injects patients (as well as himself) with recombinant human growth hormone in order to rejuvenate the thymus gland. This could help reverse aging to some extent. Dr. Fahy is described as “having thick dark brown hair and being in enviable shape for a guy of pension age.”

Hair Darkening
Dr. Fahy’s patient with hair darkening and repigmentation.

One 70-year old patient named Hank Pellissier claims that “his hair, previously white, began growing in brown”. Note that Dr. Fahy’s prescribed regimen also includes dehydroepiandrosterone (DHEA) and Metformin. More details can be found on his company website and via their clinical trials page. Also of interest, Dr. Fahy showed several of his before and after patient hair repigmentation photos at a Ted Talk in 2020. See after 13:20 mins in this video.

Update: June 22, 2022

Gene Therapy

A new gene therapy treatment for a rare genetic disease (cystinosis) resulted in major hair darkening as a side effect. Four of the five patients have gotten significantly darker hair, and the fifth just started re-growing his hair post treatment. Of note, this gene therapy entails modifying blood cells, and only changes the DNA of a small fraction of the patient’s cells.

Update: May 2022

 Nicotinamide Mononucleotide (NMN)

An interesting new video on NMN potentially reversing hair greying and skin aging. Do note that both the interviewer and interviewee are involved in the sale of NMN products. The viewer comments in there are very interesting. Make sure to also read my popular post on NAD and NMN supplements.

Update: May 2022

Minoxidil and Reversing Grey Hair

Well known dermatologist Dr. Rodney Sinclair (a big proponent of oral Minoxidil) said the following in a new Reddit AMA:

“I have seen hair darkening with minoxidil in my patients.”

Moreover, on Reddit, I have read a few posts from people stating that oral Minoxidil caused their grey hair to become dark again. In November 2022, one person even posted that after just one month of 2.5 mg/day oral Minoxidil use, his chest and beard hair become dark again. In my other grey hair cure post, I also discuss topical Minoxidil causing grey hair reversal in some cases.

Update: February 2022

Hair Graying Regulators Beyond the Hair Follicle

A really interesting study from China analyzes hair graying regulators both within and outside the hair follicle in causing the depletion and dysfunction of melanocyte stem cells (MeSCs). Emerging evidences shows that nerves, adipocytes and immune cells outside of the immediate hair follicle environment (bulge, bulb and dermal papilla) also play important roles in the regulation of MeSCs.

Update: June 2021

Stress and Premature Greying

A new experiment mapped human hair greying in relation to recent life stress events. I am very skeptical about stress causing premature hair loss or hair greying in most people. I have devoted a whole section to this popular subject in the second half of this post.

Note that in 2020, scientists from the US and Brazil also found that excess stress can turn pigmented hair white. Moreover, when cyclin-dependent kinase (CDK) protein was suppressed in mice, their fur did not change color.

Older Updates on New Grey Hair Reversal Technologies

Update: April 2021 — Harvard University scientists and a team from South Korea are developing a treatment for grey hair using pigment stem cells in hair follicles.

Update: June 2020 — South Korean researchers presented the first case of Ustekinumab-associated hair re-pigmentation. Ustekinumab is a monoclonal antibody medication that targets interleukin 12 and interleukin 23. It is used to treat Crohn’s disease, ulcerative colitis, plaque psoriasis and psoriatic arthritis.

Update: April 2020 — A new synthetic melanin nanoparticle coating method was deemed as a safer, nontoxic and longer lasting way to dye hair.

Update: March 2020Eirion Therapeutics had its patent for a grey hair treatment published. It entails using plasminogen activator inhibitor 1 (pai-1) inhibitors to prevent hair graying. Eirion’s pre-clinical product candidates for hair loss and grey hair prevention are ET-02 and ET-03.

Update: January 2020

A review of medication-Induced repigmentation of grey hair:

“As evidenced by the many cases of gray hair repigmentation in the literature, the development of gray hair may not be an irreversible process. Gray hair is a natural course of aging; however, it may not be an inevitable or permanent process.”
