Qstem: Cell-free therapy for alopecia via the secretome of hiPSC-derived dermal papilla cells

Just a few days after writing this post, more good news from Q-Stem. Their research team published a new paper titled “Cell-free therapy for alopecia via the secretome of hiPSC-derived dermal papilla cells.” Apparently, they have established a proprietary stem cell-derived hair papillary cell culture medium platform technology. This induces functional dermal papilla cells from human induced pluripotent stem cells.

Per their research results, this medium demonstrated enhanced hair growth-promoting effects compared to the control group and the standard minoxidil treatment group (via an 8-day human hair follicle time-series culture experiment). Hair growth signal activation was also confirmed. Even in a dihydrotestosterone (DHT) environment, significant hair growth responses were observed. The company plans to launch a hair loss care product utilizing this technology in August 2026. They call it an off-the-shelf cell-free hair booster for treating alopecia.

So before moving to their main goal of creating new hair follicles for implantation, Qstem will first enter the hair loss market with this cosmetic type treatment. As with other such cosmeceutical related hair loss products, this one will also not require any clinical trials.

Yet again, a new company in South Korea has announced its intention of curing hair loss. Qstem (also called Q-Stem) is a biotech company that was formed in late 2024 and specializes in treating hair loss using stem cell technology. The startup was originally founded by faculty from the prestigious City University of Hong Kong.

Qstem has developed a proprietary technology that differentiates dermal papilla cells (DPCs) from human induced pluripotent stem cells (hiPSCs) for use in treating hair loss. In February 2026, the company secured 2.2 billion won ($1.5 million) in seed investment funding.

The company’s South Korean founder and CEO Ban Ki-won is a professor at City University of Hong Kong. His h-index score is a high 29 according to Scopus (and 23 according to Google Scholar). The h-index measures the productivity (number of papers) and citation impact of a researcher’s published work. Professor Ban Ki-won’s specialties include stem cell biology, regenerative medicine and cardiovascular regeneration.

Qstem (Q-Stem): New Hair Creation from hiPSCs and Dermal Papilla Cells

Qstem plans to create brand new hair follicles for implantation. According the information here and here and on their Naver blog and in this newspaper article, they describe their technology in the below manner.

“Q-Stem’s core technology involves differentiating induced pluripotent stem cells (iPSCs) derived from a patient’s blood into dermal papilla cells (DPCs) and epithelial cells, and then forming hair follicle-like structures in vitro to induce actual hair growth.”

According to CEO Ban, while dermal papilla cells are key cells that direct hair growth, their function deteriorates easily during in vitro culture. During the research team’s progress so far, maintaining the ability to actually produce hair was a much more difficult challenge than simply increasing the hair count number.

Per CEO Ban:

“Q-Stem secured dermal papilla cells that retain hair-inducing ability through iPSC-based differentiation technology and established conditions for stable culture. Furthermore, by implementing three-dimensional interactions with epithelial cells, they created a microenvironment similar to an actual hair follicle. The core of the technology was reproducing these interactions in vitro.”

Yet another description states that the company is developing technology to secure dermal papilla cells differentiated from human induced pluripotent stem cells, extract growth factors secreted by these cells, and commercialize them.

In animal models, the research team from Q-Stem has already managed to create in vitro hair with repeated normal growth, regression, and resting cycles.

Per CEO Ban, the fact that the growth cycle was maintained implies that it is closer to a functional hair follicle (versus just a one-time structure). The company seems confident that their in vitro hair manufacturing technology has reached biological maturity from the perspective of tissue regeneration.

Q-Stem’s Three Platforms for Tackling Hair Loss

Based on this technology, Q-Stem is expanding its platform in three directions:

  1. Dermal papilla cell culture medium.
  2. In vitro hair manufacturing.
  3. Dermal papilla cell-based therapy.

This is a bit confusing, perhaps due to translation. CEO Ban has emphasized that these are not separate businesses, but rather a single regenerative medicine technology platform. It seems like different technologies will be used depending on your stage of hair loss.

According to reader “Theo” who e-mailed me about this company, the three stages are as follows per his interpretation from other sources:

  1. Dermal papilla liquor (cosmetic shampoo per the photos on their blog).
  2. Dermal papilla cells (similar to Epibiotech).
  3. In vitro production of hair follicles using hiPSCs (Stemson or Yunce approach).

South Korean laws are very strict when someone wants to use stem cells/hiPSCs. Per “Theo”, every company must build or have a partnership with someone that has a proper CMO facility for producing stem cells.

Qstem is currently establishing a mass production process for dermal papilla cell culture medium. In addition to the earlier mentioned blog, the company has a basic Instagram page with limited information at present.
