Adding SSS to this simple hair set up?

Hi All,
I’m quite new to BSDF setups and I’m wondering where the best place to add sss to this node setup?
I’m guessing I need to add a BSDF sss node with mix shader node?
The thing is I don’t know at which position in the main setup to add them, or is this not the correct approach.
Any help would be great
Cheers
A
