Weirdest question we came up with at #39c3:
If #Chemotherapy quite frequently changes hair color, is this an indicator that hair color is in part defined by an #epigenetic mechanism? Will there be pills to change hair color in the future? I’ll need to ask one of the friends who have students explore strange stuff about this…

@SporkPeter can probably answer that?

Oder täusche ich mich, @SporkPeter?

A genome-wide association study once found more than 100 genes involved in hair color, but their variants are only responsible for part of the phenotype. In my opinion, this suggests an influence of gene regulation and thus presumably also of epigenetics.

However, I have been collecting the most important news on epigenetics at https://newsletter-epigenetik.de since 2010. There is nothing about hair color. Of course, I can`t see all studies, but studies on the epigenetics of hair color would certainly have caught my attention.

@SporkPeter @cocolowres Thanks for pinging Peter. A quick glance on what is available to me as an amateur seems to agree that there’s really not much information. Even more intriguing is that the change can be drastic and permanent, in form and in color, and I’m wondering: why just (?) the hair, is it the kind of hair colors we usually express and does it tell anything abut the therapy?
Children’s hair colors can change, is this the same?
What wondrous place for the curious the world is.

To my knowledge, the change in hair color during chemotherapy is not an epigenetic phenomenon. It is simply caused by the death of cells that produce pigments. Hormonal influences, such as during pregnancy or puberty, could possibly influence the epigenetic regulation of genes that are important for hair color. But I am no expert in this field.

@SporkPeter @chris @cocolowres the question came up as since I finished chemo, my hair is acting weird. Before chemo I had straight dark brown hair. After chemo my hair came back blonde and straight. Some months passed and the new hair became dark brown and curly. Super interesting to see the changes.

@szofi @SporkPeter @cocolowres Well, very tangentially is spotted this - so there may be a very weird parallel universe where last season‘s hair color is this seasons pullover :-)
