I wasn't really sure if this should be here or health & beauty, so if its wrong just move it
My scalp is soo itchy (and now sore) and it looks like a snowfall when I comb it

I've found a shampoo I can actually use which helps my frizzy hair and stop it being too greasy, but my scalp doesn't like it! Does anyone know of some sort of conditioning treatment I could buy that would help?
I'm sick of scratching and I'm worried people will begin to think I've got nits lol!!
