Iodized salt - recommended brands

I came to know that my hair loss cud be mainly due to lack of iodine in salt, or food in general. I normally buy salt from Aldi, for 19 cents. How about you? Do the costlier ones make a difference?

I take Iodine pills because my iodine levels nearly halved after I moved to Munich.

If you buy Jodsalz it's iodized. But I don't know if the levels vary that much from brand to brand or whatnot.
