Menopause scalp itch

Thanks in advance for any suggestions.

have suffered from a crawling sensation on my scalp for years, Menopause began around a decade ago. It has times when the itching comes and goes. Has been consistent for the past 2 months.I believe it is caused by lowered estrogen levels effecting nerve ending signals.

*Crawling sensation on scalp, like insects crawling
*worse at night in bed when I feel hot.Or after exertion
*Wake up scratching viciously at scalp. Sometimes making small areas bleed
*Improves with washing hair for a few hours
*I do have hot flushes, but not as often in the past year or two
*Scalp is clean, shiny and no flaking

I've not used homeopathic remedies much in past decade or so, generally constitutionally Nux Vom works well for me.
