My B12 levels are really low again and I've developed psoriasis on my scalp :( it's really sore and itchy and last night I scratched so much I made my head bleed.
I've got thick hair and it's really hot here so lots of sweaty scalp issues :(
Is there anything I can do as a home remedy to calm it down until I can get into the GP for more blood tests and another B12 injection?
