Michelle,
Bill had Cis and Taxol so not sure which was the culprit but his beautiful full head of silver/white hair definitely thinned but did not all fall out. His hair is back to its original fullness now...really it started looking better within a couple of months after treatment ended.
The radiation field did keep some neck hairs from coming back as well and the best of all...Bill's skin is very oily but the neck and shoulder areas in the rad field are soft and clear of oil now. Only his face gets oily. Keeps his shirt collars clean.

Hey, you have to find all the good you can from this experience.
