How can i use SplineThicken node combined with hair shader for spline based hair?

Sorry I’m noob here.I’m wondering how can I use Spline Thicken node in combination with hair shader to render spline based hair strands properly. What I really need is the “visible roundness effect” that Spline Thicken gives to the splines, I don’t want the hair strands to be flat although they will be facing camera anyways. Thankyou
