Corel Paintshop PRO X9 - looking for fine detail background removal / replacement

What I want to do is 

1.  take a photo of someone with hair.

2.  select the person and any hair extending out over the background.

3.  remove the background and be left with the person and hair extending over the background.

4.  add a background that has the detail of the foreground person retained (including fine detail).

But I have not been able to get to this level with Paintshop PRO X9.

Can anyone help me?

I have included a portion of a photo which I hope illustrates the fine detail that I would like to retain.

I was hoping that in Paintshop Pro X9 that there would be something that would give me the "fine detail" that is possible in Photoshop CS6 using the Refine Edge. 

Does anyone know if this is possible? 

This is important when you want to separate strands of hair from a background. This method (follow the link below) for X6 does not do it. In fact, this was why I moved up to X7 because I thought I could get there but could not. And now wondering if it can be done in X9 which I recently moved up to. 

I suggest that if Corel really wants people to consider Paintshop to be  "PRO", they need to look at what professional software does and include features they have. That is my opinion.

Corel claims that this works better in Paint Shop Pro 2020 but I have not tested.
