A study has raised hopes for people suffering from hair loss, as researchers have discovered a protein that acts as a protective component at the cellular level for hair follicle stems.
The new treatments might be able to target the underlying cause of receding hair rather than its symptoms, according to the study published in the journal Nature Communications.
The research centers on a protein called MCL-1, which the scientists found plays a critical role in protecting stem cells during the hair regeneration process. When that protection fails, the cells self-destruct and halt new hair growth entirely.
Hair follicles cycle continuously through phases of growth, regression, and rest. During the activation phase, when stem cells divide to generate new hair, they are placed under significant biological stress — and it is precisely at this point that MCL-1 appears to be essential.
When researchers removed the MCL-1 protein from skin cells in mice, the follicles developed normally in early life. Over time, however, as stem cells attempted to activate and regenerate hair, they collapsed under the stress and withered, leading progressively to hair loss and follicle destruction.
By stabilizing the MCL-1 protein or reducing the death of cells due to stress, future treatments could protect stem cells at the regenerative phase.
Encouraging news has also emerged from Schweitzer Biotech Company, which says a new plant-based serum achieved a 25% increase in hair density and thickness within eight weeks. According to the company, the difference lies in the use of scientific methodology rather than testimonials from social media.
The study was published on the medRxiv platform, but has yet to be peer-reviewed. Although the results were encouraging, research is still at a preliminary stage.
Until long-term clinical trials are completed in individuals with actual hair loss, this new plant-based approach remains promising, but its clinical value has not yet been fully established.
