Half of All Men Lose Their Hair but Scientists Just Found a Natural Sugar That May Grow
Hair loss is far from a rare concern. Up to 50 percent of all men will experience male pattern baldness at some point in their lives, a condition driven by a combination of genetics, aging, stress, and hormonal changes. Despite its prevalence, only two drugs have ever received FDA approval to treat it, a figure that researchers themselves describe as remarkably limited, and one that the new findings could, eventually, help to change.
The compound at the center of this research is 2-deoxy-D-ribose, known scientifically as 2dDR. It is a deoxy ribose sugar that occurs naturally in the human body, and it has been under investigation at the University of Sheffield and COMSATS University Pakistan for the better part of a decade, not originally in connection with hair, but as part of a broader study into wound healing.
Eight Years of Wound Research That Led Somewhere Unexpected
The discovery came somewhat sideways. For eight years, researchers were studying how 2dDR could help heal wounds in mice by promoting the formation of new blood vessels, a process known as angiogenesis. Over time, they noticed something that had not been part of the original research design: the hair surrounding those healing wounds appeared to grow more quickly than in untreated areas.
That observation opened a new line of inquiry. According to a 2024 study published in the journal Frontiers in Pharmacology, the team then developed a model of testosterone-driven hair loss in mice, specifically designed to mimic human-style male pattern baldness. When a small dose of 2dDR was applied, the formation of new blood vessels followed, and so did hair regrowth, within weeks.
The results, as described by the authors, were measurable across multiple indicators. The mice “demonstrated an increase in length, diameter, hair follicle density, anagen/telogen ratio, diameter of hair follicles, area of the hair bulb covered in melanin, and an increase in the number of blood vessels.“

How It Compares to Existing Treatments
The two drugs currently licensed to treat male pattern baldness each come with significant limitations. Minoxidil, sold under the brand name Rogaine, is a topical treatment approved for both men and women. Finasteride, sold as Propecia, is taken orally, has been linked to side effects, and is not considered suitable for women.
According to the study, 2-deoxy-D-ribose proved as successful as minoxidil in regrowing hair, with both treatments showing between 80 and 90 percent effectiveness in the mouse model. For a compound that is naturally occurring, inexpensive, and stable, and which can be delivered through a variety of carrier gels or dressings, that result carries some weight.
Muhammed Yar, associate professor at COMSATS University Pakistan, noted in a statement that these characteristics make 2dDR “an attractive candidate to explore further for treatment of hair loss in men.“

Promising, but Still Early
The scientists involved are careful not to overclaim. Sheila MacNeil, emeritus professor of tissue engineering at the University of Sheffield, described the findings as “very much early stage” while affirming that “the results are promising and warrant further investigation.” She framed the approach in straightforward terms: “the answer to treating hair loss might be as simple as using a naturally occurring deoxy ribose sugar to boost the blood supply to the hair follicles to encourage hair growth.”
According to Popular Mechanics, MacNeil believes the team is nonetheless on track toward something genuinely new, a mechanism of action that targets circulation at the follicle level in a way that existing approved options do not. “This could offer another approach,” she said, “to treating this condition.“
The path from mouse models to human treatment remains a long one, and no timeline has been proposed. But for a condition affecting half of all men, a naturally occurring sugar that the body already knows may be worth watching.
