Intermittent fasting resulted in a hair growth speed reduction of 18% in adults who practiced the diet compared to controls who were eating a regular diet, a new study found.

A new study found that mice subjected to intermittent fasting — which involves limiting eating to a certain daily window — had better metabolic health but slower hair growth than mice with round-the-clock access to food. And when they studied the same thing in humans, they found similar results.

New research shows that intermittent fasting, while beneficial for metabolic health, may slow hair regrowth by impairing hair follicle stem cells (HFSCs).

Researchers said they don't want to scare people away from practicing intermittent fasting as it is associated with a lot of beneficial effects.

Many employ what is referred to as intermittent fasting, a broad term for various ways of alternating between eating and fasting periods. Research suggests it's safe for many people, and may offer health benefits,

Intermittent fasting has proven benefits for metabolic health, but a new study shows that it could slow hair growth -- at least in mice. Researchers report that mice subjected to intermittent fasting regimes showed improved metabolic health but slower hair regeneration compared to mice with 24/7 access to food.
