Hair Transparency issue

on 4.6 i had no problem with hair but at 4.7 i cant get a nice transparent hair look.

i cant seem to get this in lighting render to come out right.
I like hair that produces shadow and has soft transition of transparency. I dont see it at this version. i am using the foliage 2 side but i get wierd lighting on the hair. I could use some tips.

I made this tutorial for pretty much exactly this, if it helps you out, share it with friends!!
