My dad just finished his 9th round of Sutent and within the first two rounds, his hair and beard turned completely white. His skin changes colors... sometimes kind of yellow, sometimes grey, sometimes flushed like he's been in the sun, others very pale... during the two weeks off, he usually looks pretty normal. Good luck with the sutent though! His real complaint is the sore mouth and easily upset stomach along with the fatigue in the 3rd and 4th week. Prayers and best wishes!
