Hi Dianna, thanks a lot for that!
It will take me a while to digest the amount of information and check all the sources. Thank you very much.

On some of the ponts: I love my read meat. I know that it's supposed to be bad for hair, but I have a vegetarian colleague with a vegan girlfriend and he too is losing his hair so.... I'll stick to the steak for now
Also, when I take PM I drink loads of milk and eat as much cheese as I can (for science, obviously) so veganism is really not for me.

Green tea is doable. I am not a big fan, but I have some at work and I could start drinking it more frequently. I don't drink spearmint tea. I don't like the taste of mint in any form, so that's really beyond me.

I'll have a look soon at all the other advices.
For the moment, thanks a lot again!
