Making Hair Tip Thinner and Questions About Strand Renderer

[CakemonBot]

Is it possible to change the hair size, and make the root thicker and tips thinner?
I guess it could be something to do with strand renderer - built in strip, but using this setting I cannot use custom material, nothing will be rendered in the scene.

My work flow:
Set up a hair instance object> set strand renderer to built in strip, scale up strand diameter and hair can be seen rendered, but in same length
Setup a shader like so

Apply it to the hair and the hair works weirdly

And if it required some shader knowledge it will be great if a sample shader can be provided, it's a bit advanced for me :)

Thanks for the workflow description. :)

Being able to visually modify the width of the rendered strands via ShaderGraph is a feature in progress.
