When I was in my teens I suffered terribly from dermatitis on my hands, mainly my palms, nothing would cure it, my life was disrupted by my problem. I went to many GPs with no results. Then a pharmacist gave me a mixture of coal tar ointment, told me to apply it at night and wrap my hands in clear platic wrap every night, for, I cant remember how long, a week maybe, it smells very strong, but I perservered. After applying this treatment, I have never suffered from dermatitis on my hands again, I am now in my fifties. Hope this may help someone.
