That's a good point about the chemo, Chick. Having had chemo appears to make a great deal of difference to treatments following on, such as endocrine therapy and radiotherapy.
Here's a bit on the Cancer Research UK site about dying hair after chemo.

Using hair dye
It is best not to use dyes or perms for around 6 months after finishing chemotherapy. This is because when you are recovering from chemotherapy, your hair is more fragile than usual. It is more likely to get damaged.
It takes about 6 months for the hair to become stronger. It isn't a good idea to use:
- permanent hair dyes
- semi permanent hair dyes
- perms
These products contain strong chemicals that can damage your hair. Your scalp may also be drier and itchier than normal during this time. Using strong chemicals on your hair can make this worse.
Henna and vegetable based dyes
It's understandable that you might not want to wait to dye your hair. You can ask your hairdresser to suggest henna dyes or vegetable based dyes for you. These are gentler on the hair than the other types of hair colouring. So hair specialists think it is safe to use them.
Even with a vegetable dye, it is worth testing before you use it. You can test the dye on a small section of your hair first to see how it works.
How chemotherapy might affect your hair
This will depend on which chemotherapy drugs you had. Some types of chemotherapy make hair fall out completely. Other types make the hair thin, or change in texture.
You might find that your hair doesn’t grow back exactly the same as it was before. Here's some possible changes that might happen to your hair:
- the colour may change
- the texture may be different
- your hair may be more curly
- it may be straighter
I can't find anything on Breast Cancer Care, Cancer Research UK or Macmillan to suggest that readiotherapy to the breast affects the hair on you head.
