The new shampoo arrived today. It's actually a combined body/hair wash made in UK by Alamay. I will start using it tomorrow.
I haven't noticed my eyebrows changing colour since using BP on my face. I usually get some on my eyebrows as I use it all over my face. Perhaps as you have very dark hair, it is more noticable. I also use BP on my chest & it doesn't appear to have bleached my chest hair although, as I say, I do have light coloured hair (that's where it hasn't already gone grey lol).
If this new shampoo doesn't help, I may try a blob of BP mixed in with my face wash as a shampoo. I will keep some Grecian 2000 handy just in case! 
I am honoured to be your guinea pig. LOL.
