Hair/Skin Concerns

Has anyone noticed changes to their hair after starting MTX? I got diagnosed with RA a few months ago and started on MTX pills. I knew hair loss and thinning was a possibility and I am noticing some of that, but also my hair gets super greasy in like a day now? I used to be able to skip a day between hair washes, now I feel like by mid day you can SEE the grease build up on my roots when I just showered right before I went to bed that night. Also, I've got horrible, painful acne all of a sudden. I used to be blessed with pretty clear skin, and only have a minor hormonal breakout around my period. Now its 24/7 deep, painful zits that wont go away for days and cant be physically popped. Seriously at my wits end here...
