I read where one dermatologist (who specializes in hairloss) claims that whey isolate protein causes hair loss but whey concentrate (cheaper, less refined) does not. How could that be? To my knowledge, protein supplements do not affect hormonal levels at all. Do you know of any reputable studies to that effect? I take a whey isolate protein that agrees well with my stomach and I do not want to give it up unless there is some truth to that. Thanks for this blog.
I would also agree and ask “how could it be?” I don’t know of studies that backup those claims. Perhaps astute BaldingBlog readers can point us in the right direction.
Did your specialist offer an explanation?
