Hi everyone, this is the problem.
I had try different type of shader but none resolve the problem. Any solution?

Hi Gamit,

We've been aware of this issue. Due to the rendering mode of both hair and scalp are fade, there are some transparency sorting issues in the unity. However, if changing the rendering mode of scalp from fade to cutoff, there will be visual flaws. While waiting for Unity official shader, we will continue to survey and try to find a solution to implement.
(It's reported by other game developers before, for example)
