Hi Uncutandgettinglonger
APPLE CIDER VINEGAR. I get really bad dandruff/flaky scalp and sometimes eczema on my forehead and eyebrows.
I found this remedy on a website, which is use apple cider vinegar daily for a week. I put neat vinegar in a spray bottle (you can dilute it if you want) and sprayed my scalp all over, left it on for half an hour, then washed and conditioned. Shampooing, not forgetting behind your ears and stuff will get rid of the smell completely. It works your scalp will be clear in a week!!
It also works better than any shampoo I've ever tried including Selsun and Nizoral.
If you miss any spots on your scalp, or get dry skin on your forehead you can dab vinegar on using a cotton ball before bed. The smell will evaporate over night, and most if not all the flakiness will be gone.
After daily treatment for a week you only have to do it once a week or even a month. I also shampoo out with T-gel anti-dandruff for dry hair (it smells really nice and is a mild anti-dandruff shampoo) as extra back up as if you miss a spot it can become flaky again. Good luck!! This has really helped me manage my dandruff. Plus, apple cider vinegar is really cheap. My health store sells a litre for about £2.
I think this only works if your flaky scalp is caused by yeast though, I don't think it works if you have psoarisis but it's worth a try you might have the one caused by yeast (the one that T-gel, Nizoral, etc treats)
