Intermittent fasting can be effective for weight loss, but it can also have negative effects on hair growth, as shown in a recent mouse experiment conducted by researchers at Westlake University in China. The study found that mice undergoing intermittent fasting experienced improved metabolic health but showed delayed hair regrowth. This link between restrictive eating and hair regrowth was also observed in a study published in Cell.
While similar effects may occur in humans, they are typically less severe due to differences in metabolic rate and hair growth patterns. Nevertheless, it is important to be aware of the potential unintended consequences of intermittent fasting, as highlighted by senior author and stem cell biologist Dr. Bing Zhang.
Further research is needed to fully understand the effects of fasting on hair growth, as current studies have primarily focused on its benefits for blood, muscle tissue supply, and metabolism. The research team at Westlake University conducted experiments on mice to explore the impact of intermittent fasting on hair regrowth, with findings suggesting that prolonged fasting stresses hair follicle stem cells, leading to delayed hair growth.
A small clinical trial involving 49 healthy young individuals showed that time-restricted eating with 18 hours of daily fasting reduced hair growth by an average of 18 percent. However, the researchers caution that the study’s small sample size and short duration may yield different results in larger-scale studies.
Future research will investigate how fasting affects other types of stem cells in the body and its implications for wound healing speed. Despite the potential drawbacks, intermittent fasting remains a popular and beneficial practice for many individuals.
