You delete all lights.

And your hair glows?

What does that tell you?

Check that there is NO Ambient on the hair. (Ambient_Color or Ambient_Value.)

Uncheck Light emitter on the hair properties.

PS : all Diffuse + Specular nodes combined can not be higher then 1.000

You can never have more light going out then coming in.

Post a screengrab of the hair shader so BB (or others ) can have a look at it.
