Fatty acids can restore hair growth.
Scientists from Taiwan have discovered that fatty acids can awaken "dormant" hair follicles and restore hair growth. The study, published in the journal Cell Metabolism (CM), showed that with mild skin irritation, fat cells begin to break down fat and release monounsaturated fatty acids — primarily oleic acid. These substances are absorbed by the stem cells of the follicles and activate them through metabolic signals, enhancing mitochondrial function and energy production.
In experiments on mice, simple topical application of fatty acids led to the emergence of new hair within just 10–20 days. When researchers blocked fat breakdown, growth ceased, confirming the key role of this chain. The scientists describe the process as "metabolic communication" between fat cells and skin stem cells, triggering regeneration.
According to the authors, the discovery could lead to the creation of a new generation of safe and inexpensive treatments for baldness — without hormonal side effects and relying on natural tissue regeneration processes.
