Good afternoon. I've been dealing with painful nerve impulses in my scalp and diffuse hair thinning since applying a hair dye in Nov 2014. I have seen a myriad of doctors about these issues. I've been prescribed everything from topical steroids to antidepressants- causing many side effects, I might add. I'm now off all meds and supplementing with Sunflower Lecithin& Brewers yeast for B vitamins. Is there anything else out there that can relieve my scalp pain and stop the thinning? Please help.
