GF skin suffering bad, no insurance. please help!!!

My gf is in the usa studying from sweden. Ever since she moved here her eczema has flared up extremely bad. It is all over her upper half, and when she showers (even if its not hot water) her whole skin is red and hot. Back home it was very minimal, she had hydrocortisone for flare ups but barely needed to use it. She has tried so many remedies, and she has even tried to visit an allergist but her insurance is essentially emergency insurance so it does not cover allergy tests/ prescriptions. Is there any natural, over the counter way for her to get relief? Shes also trying to avoid anything with steroids to not become reliant and face issues later in life

She has taken Allegra, uses scent free detergent, thick scent free eczema approved lotion, has tried oatmeal baths (unsure if that helps), and is a vegetarian so her diet is pretty healthy.

She will try anything at this point and ultimately she does not want to just leave school to go home, she wants to get her degree.

thanks for any insight and suggestions!
