Will the curls stay? Plus trouble growing eyebrows

Here are the photo I tried to post on my personal response.

Hair  just after surgery

Hair post chemo ...5 months on

Hair product I swear by plus regular trims to get rid of frizz and give it style


I'm 52. And not a Nanna and thinking of uploading my sons profile into a dating app to help them along, lol. 

I don't want to colour my hair but we will have to wait and see.
