Intermittent fasting could reduce hair growth, study reveals

Intermittent fasting has become a popular trend in recent years for its potential health benefits, including weight loss, improved heart health, and enhanced memory. However, a new study from Westlake University in Zhejiang, China, suggests that this eating pattern may have some unintended consequences when it comes to hair growth.

The study, published in the journal Cell by Cell Press, found that intermittent fasting could significantly reduce hair growth in both mice and humans. Researchers observed that mice following different fasting schedules exhibited slower hair regeneration compared to those with a normal eating schedule. In a human clinical trial involving 49 healthy young adults, fasting for 18 hours per day was associated with an 18% reduction in hair growth.

Dr. Brendan Camp, a board-certified dermatologist, explained that the metabolic changes triggered by fasting may create oxidative stress that hinders hair growth. This stress on hair follicles can disrupt the growth cycle and lead to slower regeneration. To counteract these effects, Dr. Camp recommends focusing on a diet rich in essential vitamins and nutrients like iron, selenium, zinc, biotin, folate, and vitamin D to support healthy hair growth.

While the study sheds light on the potential impact of fasting on hair health, it’s important to note that individual responses may vary. Crash diets or sudden weight loss can also contribute to hair shedding and conditions like telogen effluvium, where hair loss occurs in response to physical illness or stress.

The research was supported by various institutions in China, including the National Natural Science Foundation and the Key R&D Program of Zhejiang. Fox News Digital reached out to the study authors for further insights on their findings.

In conclusion, while intermittent fasting may offer various health benefits, individuals should be mindful of its potential effects on hair growth. Maintaining a balanced diet and consulting with a healthcare provider can help minimize any adverse impacts on hair health while reaping the benefits of intermittent fasting.
