I have had subhorreic dermatitis for about a year on the back of my head and around the top of my left ear. I have used a couple different prescriptions that made the itching bareable and kept the oozing to a minimum (sorry that's gross, I know). A friend told me about GSE so I figured I'd give it a try on this as well as some atopic dermatitis on my legs. It did wonders for my head and helped my legs some too (though I didn't stick with it and it flared up again, time to get back to it I suppose). I also experienced the stinging/burning but I've found that dilluting a bit more can make a world of difference. I read that it's very powerful in small amounts so it doesn't need to be extremely concentrated to work. I just rinse my hands with water then put a few drops of GSE on my hands and rub them together. Then I just rub my damp hands over my legs or head. You can also put a dilluted solution in a spray bottle (worked nicely for my head). I'd recommend playing around with the concentration that feels good as you don't want to irritate the skin more than it is already. If it burns, water it down a bit (I've read you can diluted it in olive or coconut oil too but haven't tried that). If you don't feel anything, maybe add a couple more drops? I personally like to feel a little tingle but no burn. Good luck!
