Humira & Methotrexate - Third Colonoscopy

I was just wondering about some possible side effects I may be experiencing with Humira and Methotrexate.  I take my Humira injection and Methotrexate once a week.  Since I've started taking them I have noticed that my hair is starting to fall out and no matter what conditioner I use it stays very dry and brittle.  I've also noticed that my skin is drying out more.  I have rough dry patches all over and no matter what type of lotion or body wash I use it doesn't seem to help this problem either.  Anyone else have either of these two issues and have any suggestions?  Oh and wish me luck.  I'm having another colonoscopy on May 10th to see if I'm healing and to look at my obstruction.  Anyone have any suggestions on how to make my scope easier?  This will be my third time and each time I've asked to use osmoprep because I have a hard time drinking any of that stuff that cleans you out but then with the pills I also get to a point where I start vomitting after so many rounds of those.  So any suggestions?  Thanks my Crohn's family! 

I had dry itchy skin, that would turn red, then heal much whiter than my normal skin tone. I used Cetaphil lotion and a sensitive skin body wash. That seemed to stop the itching, but the skin is still patchy white. Possibly taking a multivitamin would help.
