You can use any hair that you like. Just rescale the hair using the scale dials in the parameter dials. Scale, X Scale, Y Scale, Z Scale.  You may also need to use Y and Z Trans.

Right click in the scene and pick the AUX Camera or POSE Camera so that you can move around to different angles to check the fit.

Once you have the hair fitting the way you like, go to "OBJECT" and "Change Parent', and select Aiko's head.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
