Hey Alexander!

Also, Mike's right about the melanocytes, but theoretically we could control how late the melanocytes die off through genetic engineering (so they produce the colored melanin longer). This is supported by the fact that twins almost always have similar hair greying patterns, suggesting a link to genetics.

I believe it generally ties into the death of the cells responsible for pigment development, and has a pattern similar to death of follicles in male pattern.   There are some prevention methods to keep those cells alive longer, but I only know one method thats ever regenerated the dead cels, and it wasn't supposed to.

Hi DIYbio community,

I was wondering if there could be any "system-biological" approach to "cure gray hair" and prevent the hair from losing its colour.
What is known about the genetic and the epigenetic mechanisms that cause the colour loss of our hair?
There are some interesting patterns, for example the fact that usually the hair around the temples starts to lose its colors first.
Which expression patterns can be linked to these observations?
And what would be promising ideas to interact with these mechanisms?

Thank you for your ideas

Mike
