I noticed you have had your question in for 12 days so I decided you needed to know you are not alone.
I know I am gluten-intolerant but have yet to be diagnosed with anything. I have been doing a lot of studying on Celiac Disease and am sure these is relief from it...maybe not a "sure-cure" but relief.
I, too, noticed a lot of hair loss but have done 2 Liver Flushes in the past year and have noticed new hair growing in those thin places. I don't know what caused the hair loss. Maybe parasites, maybe the dermatitus, but I do believe the parasite cleanses then Liver Flushes and the gluten-free diet has been the big help in that.

Intolerance to certain foods can cause diarrhoea during which there is a loss of vital fluids which can lead to symptoms like hairfall etc. Homeopathic Medicine has good remedies to get rid of the intolerance and improve the absorption and meanwhile some remedies like Ac.flour, Lycopodium would arrest hair fall too.
