As promised here is a Simple Cycles shader for Transparency Hair. Simple Transparency.zip As with the previous shader you can install it just like any other item from the store. It will be found under the materials tab in a folder called 'Transparency Hair'. Here are some "quick" instructions on how to use it.
Load the shader into the scene using the double checkmark. Once it's in the scene connect the 'color' control to the hair's texture and the 'Opacity Map' control to the image we normally refer to as the transparency map.
If the hair uses a bump map or height map it can be attached to the 'Bump' Control. The 'Bump Strength' value controls how strong the bump map is.
The next control is the 'Normal' control. This is used for attaching normal maps to the shader for displacement. Please note, do not attach a normal map directly to the 'Normal' control. In cycles and Superfly you must connect the 'Normal' controller on the 'Hair Shader' node to a 'NormalMap' node. This is accomplished by right-clicking a blank spot in the Material Room and a menu will pop up. On that menu at the very top it says 'NewNode'. Hover over 'NewNode' and an extension to the current menu will pop up. At the bottom of the new extended menu above the word 'Compound' will be the word 'Cycles'. Hover over 'Cycles' and another extension to the menu will pop up. On the new extension hover over the word 'Vector' and you guessed it; another extension to the menu will pop up. Finally from this newest extension to the menu you can select 'NormalMap'. A 'NormalMap' node will be created. Connect the 'Normal' control to the 'NormalMap' node where it says 'Normal'. On the 'NormalMap' node connect the 'Color' control directly to the normal map. Sounds easy right? Since it doesn't sound easy to me I'm going to add some images above this paragraph after I type it.
The last two controls on my 'Hair Shader' node go hand and hand. The 'Bright' and 'Contrast' together generate the translucency color of the hair just like my strand shader does. Just like the strand shader the default settings will produce produce a realistic color on most hair colors. The only exception is on blond and really light color hair. In those cases just set the contrast to 0.
I should have mentioned this on my last shader as well, but I thought it went without saying. Any shader I make and post in this thread you are free to use in any way you see fit.
I hope everyone finds this shader helpful. If you have any questions, comments, or concerns feel free to ask, and I will answer them to the best of my ability.
