This is sheer vanity, I know, but I am starting to go grey and wondered about whether, it is safe to colour hair whilst taking MTX and Sulfasalasine? The. MTX has been reduced due to brain fog and hair loss but the rheumatologist says that lowering the does will help. And the Sulfasalasine has just been added in. But I don't want to colour if it will just make more hair fall out. So I wondered if any one else has any experience with this. Thanks, Clemmie.
