I'm not sure about flushing out fungus - someone with more knowledge on that could better advise you.
However, I add one level teaspoon of Borax to one liter of water and use that as my concentrate, from which I take 20mls, twice daily, in a glass of water. Lesser amounts, I found, didn't seem to have any effect on my system - but then again, my body has been very ill for just over ten years, so perhaps it takes a bit more for someone like me.
As for hair loss, have you tried dispensing with commercial hair products and instead, using your Borax 'Concentrate' to wash your hair with? (You can make up a separate bottle of the concentrate for washing hair to leave in the bathroom.)
Of course, it doesn't lather, but it does feel slippery when you pour it onto wet hair, so you know where it is when you touch your scalp.
Just let it sit in your hair for a moment or so (or you can 'scrub' if you like as you would with shampoo), and then rinse thoroughly.
After that, rinse with the same dilution of citric acid in water (1 level teaspoon in 1 liter of water) and pour over scalp and hair.
Rinse out the citric acid 'rinse' - and you're good to go.It's a lot less fuss than commercial products and a lot less damaging to scalp, hair, eyes and skin.
