For the women -genes, not stress causing grey hair.

Those grey hairs you are plucking (if you are lucky) or dyeing may not be caused by the stressors in your life.  “Yeah, whatever,” you say?

A Danish study (This one was cherry) of more than 200 twin sisters (identical and not) aged 59-80 conducted by Unilever scientists had found no significant differences in hair color among the identical twins.  Identical twins share the same genes.  There were significant differences between non-identical twins.

Anyone else confused by this?  You should try reading the original.   Let me paraphrase what is likely a paraphrase from the original.  There is good reason to believe that there is a genetic basis for grey hair and that your life-style is not determinative. Better?

Now about the thinning hair, it seems that receding hair in women is, in fact, related to environmental factors. This all runs counter-intuitive to what the common public belief is suggesting that either the common public is wrong (which could happen) or that something is being lost in the translation.
