Does Stress Cause Gray Hair?

A recent study in mouse models published in Nature and performed by scientists from Harvard University showed that hair graying is associated with acute stress through the fast depletion of melanocyte stem cells. The results of this study advance knowledge of how the body is affected by stress, and are a first step toward blocking its negative effects.

  • One year ago, I received a large research grant for a multi-center investigator-initiated research trial. While that was very exciting for me, I felt a big burden had been laid on my shoulders. How to write a detailed proposal, finalize the budget, get contracts, IRB approval, coordination with other centers, …. At that point, my research team got in touch with Phoenix CR, a well-respected regional CRO. Over the ensuing 12 months, the Phoenix CR team, proved to be of great help. A very reliable group of individuals, well familiar with the whole process, helped me and my team go through all these steps with little difficulty. They put up with hundreds of meetings and emails and phone calls, while maintaining a professional attitude and a very receptive accommodating behavior. I am sure, my journey through that process would have been much harder without this wonderful team. Thank you, Phoenix CR Team for everything.
