Have you looked into UVB lamps?

Had a friend talking about them, but they seem to be prohibitively expensive. Do you have positive experience using such lamps?

I tend to have some eczema on my scalp that sun really helps with.

Maybe a lamp that costs the equivalent of a week of holidays in a warm place could be justified after all.

I don't have any experience myself but they do seem to be effective. Yeah, I think you'd have to compare it to a holiday, or how much time that would mean in a Solarium.
