Get a clean spray bottle and break up about 1-2 Tablespoon size chunks of alum. Put this in about 1 cup of water and then fill your spray bottle with it. I spray a few sprays on my hair and massage it in my scalp. Some under arms for deodorant and then I give a few sprays all over my limbs and body, rubbing it into my skin. It has a weird texture; it seems to sink into your skin quickly - that's why the spray works so well. I'm thinking of trying an application in the evening as well and maybe by then I'll have more of a cure. Experimenting with the frequency... Let me know how this works for you. I used to have bad eczema in my hair that would flake all over; very embarrassing. I cured it by soaking my head with straight ACV and covering that with a shower cap overnight, but I don't like smelling like a pickle throughout the day. :) Now, the potassium alum has prevented it without the smell. Good luck to all, and hopefully we can cure our debilitating eczema.
It is important to use the correct amount of topical steroid for your eczema, as instructed by your healthcare professional. Topical steroids should be applied with clean hands so that the skin just glistens. It can sometimes be difficult to judge how much steroid to use and there are guidelines on the amount required to cover body areas that are affected by eczema. These are based on the Finger Tip Unit (FTU), and explained in detail in our fact sheet which you can download as a pdf from the related documents to the right of this page.
A more novel form of treatment involves exposure to broad or narrow-band ultraviolet (UV) light. UV radiation exposure has been found to have a localized immunomodulatory effect on affected tissues and may be used to decrease the severity and frequency of flares.   In particular, the usage of UVA1 is more effective in treating acute flares, whereas narrow-band UVB is more effective in long-term management scenarios.  However, UV radiation has also been implicated in various types of skin cancer, and thus UV treatment is not without risk.
