Scalp just annoying

Hi everyone 

OK so I have Grade 3 Breast cancer and have had a left mastectomy.

 

I am in my 3rd week after my 1st cycle of FEC Chemotherapy on 11th November.

So far so good apart from my head hurts!!

My head is just tender to touch and uncomfortable to lie on.

Any suggestions on a kind of shampoo to use, they said an oil based one?
