Due to start chemo in next few weeks - question about acrylic nails and hair dye

1. I feel really silly asking about something that feels so fickle at the moment.   I just wanted some advice because I've got some pre-made appointments coming up and I'm not sure if to cancel them or not.

I was diagnosed with breast cancer 5 days ago.  I've been told that chemo will start just before or just after Christmas. 

Can people undergoing chemo have acrylic nails or manicures?  I get mine done regularly and have an appointment on 22/12 and want to know if i should just get them removed and go natural ahead of the treatmentstarting?  I imagine my nails will be weak durring and after chemo?

Also I get my hair bleached.  I'm due to have it done on 23/12/23 and its expensive.  Can someone's undergoing chemo continue to have their hair coloured? I know there is a high chance I will lose my hair.  I'll be having the freezing cap with my treatment which I was told works for 1 in 3 people.  But I'm not sure if i should just cancel it and save the money.

Can anyone advise please?
