Title more for attention, but it does really feel that way.
Back story: had a bit of dry scalp which looked gross and flakey, so used head and shoulders. It did nothing, and made my scalp itchy when it hadn't been itchy before. Switched to vosene which seemed to make a small difference until yesterday when I washed my hair. I dried it and when I ran my hands through it, felt lumps on my scalp. Got DH to have a look and my scalp is flaking in a big way. Flakes are around 1cm across, quite thick and it looks horrendous.
I'm prone to a bit of eczema occasionally, I have asthma and a few allergies, so generally an allergic type. But I've never experienced this before. We've not long moved house, and the water here is much harder than where we lived before. It's affecting my skin a bit, but this seems to be a sudden change.
It sounds like a first world problem I know, but it looks horrible and I'm dreading going to work tomorrow and covering everything in scalp dust 
I've got a GP appt next week anyway, so might mention it to her but I feel such a tit saying 'oh by the way, my scalp is minging, can you fix it?'
Anyone have any decent remedies I can try in the mean time?
