Hi can anyone give me any advice

im 7 cycles into chemotherapy and now have a very itchy scalp, with what looks to be an outbreak of spots over it aswell

its driving me crazy trying not to scratch it as it's then becoming sore and is already very tender 

i did have my head shaved but that would be about 3 weeks ago, a friend who has had breast cancer suggested coconut oil, I've tried this but it's just not working 

I'm not due back at chemotherapy until Wednesday but am wondering wether to phone them tomorrow for advice xx
