"poses no danger to your hair" I keep hearing folks say this, and even in this thread there's someone who's experienced that and had it stop when they eliminated creatine. I too have experienced exactly that with exactly the stopping of issues once I stopped taking creatine.
Perhaps you can say "danger to your hair is rare", but there's very clearly (to me at least) an effect there, and the way it gets hand-waved away is strange to me.
