Scientists at National Taiwan University (NTU) in Taiwan have developed a brand new topical serum that’s reported to cause hair regrowth in nearly 20 days in laboratory animals.
Study results published within the journal Cellular metabolismdescribes how natural fatty acids were applied to the shaved skin of mice and recent hair growth was observed inside 20 days.
Principal investigator Sung-Jan Lin even reports a limited self-test on his own legs through which he observed hair growth after about three weeks of using the fatty acid solution.
Although the outcomes are very promising, scientists emphasize that the treatment remains to be on the preclinical stage and has not yet been proven in large human trials.
How the serum works
The key to this discovery is knowing how the body sometimes regenerates hair after skin damage. The NTU team relied on a phenomenon called hypertrichosis – increased hair growth in consequence of irritation or damage to the skin.
In their experiments, the researchers applied a light irritant (sodium dodecyl sulfate) to the shaved skin of mice, which stimulated immune cells (macrophages) to infiltrate the fatty layer beneath the skin.
These immune cells then stimulated adipocytes (fat cells) to release monounsaturated fatty acids (MUFAs) akin to oleic acid and palmitic acid.
These fatty acids were then taken up by hair follicle stem cells via a transport protein (CD36) and activated a metabolic regulator (PGC-1α) that helped get up dormant hair follicles.
The breakthrough got here when scientists discovered they might bypass the irritation stage entirely by applying fatty acids directly as a serum, which resulted in hair regrowth in mice in about 20 days.
Why that is potentially necessary
Current hair loss treatments – akin to minoxidil or finasteride – typically give attention to blood flow or hormonal pathways and sometimes require long-term use with various degrees of effectiveness.
NTU Serum represents a novel approach: fatty acid-mediated metabolic signaling goals to stimulate hair follicles, somewhat than simply stopping hair loss or mildly stimulating existing hair follicles.
Because fatty acids occur naturally within the body and in vegetable oils (for instance, oleic acid in olive oil, palmitic acid in some nuts and oils), the security prospects are more favorable, although they’ve not yet been proven in humans.
If human studies confirm this effect, it could turn into a more natural and easier to use topical solution for many individuals scuffling with thinning or baldness.
Limitations and things that also must be proven
Despite the joy, just a few major caveats remain. First, the 20-day regrowth effect has to date only been achieved in mice, whose hair growth cycle is far faster and whose physiology is different from the human scalp.
According to NDTV, one among the expert summaries clearly warned: “studies in mice don’t robotically translate to ends in humans.” Second, its use in humans has not yet been thoroughly tested – no large-scale randomized human clinical trials have been published.
Third, the laboratory treatment context included shaved mouse skin and controlled application; Actual human scalp conditions (e.g., androgenetic alopecia, pattern baldness, scarring) are rather more complex.
Finally, although the ingredients are naturally derived, topical use of the concentrated product should carry risks (irritation, changes within the skin microbiome, unexpected effects) that must be verified in human safety studies.
What’s next?
A research team from NTU has filed a patent application for the serum, indicating plans to maneuver toward human testing and potential commercialization.
The next steps will include clinical trials to find out effective dosage, frequency of use, safety on the human scalp, and long-term results (whether regrowth is everlasting and the way it pertains to various kinds of hair loss).
If successful, the serum could turn into an over-the-counter topical product somewhat than a more invasive or pharmaceutical treatment.
It is advisable to proceed with medically approved treatments, scalp care, nutrition and dermatological advice until more human evidence is out there.
