1. **How Stress Causes Gray Hair** by NIH News in Health - (Trust Score 9/10)

- A study shows that stress can lead to gray hair by causing the loss of melanocyte stem cells in the hair follicle, which are responsible for producing pigment. This is linked to the body's fight-or-flight response and the release of norepinephrine into the follicle[1].

2. **Human Hair Graying is Naturally Reversible and Linked to Stress** by PreLights - (Trust Score 8/10)

- This study indicates that hair graying can be induced by stress but is reversible. The study found that periods of stress corresponded with the time at which graying occurred, and cessation of the stressful period corresponded with reversal of graying[2].

3. **White Hair: Causes and Prevention** by Good Health by Hims - (Trust Score 7/10)

- While not the primary cause, extreme stress can contribute to premature graying. The study on mice showed that stress triggers the release of adrenaline and cortisol, leading to the depletion of melanocyte stem cells necessary for hair color[3].
