Why not just to connect BSDF output to the Volume instead of the Surface?

alpha transparency is animated through brightness…if i connect to volume i see nothing…never… at frame 25 i want to see the hair completely…from 0 to frame 25 a transparency progress from 0 to 100 percent

question is ,what remains…is it shadow, is it doubleface…is it AO…?
