ArrayHairSystem is your array not the size of your array. In your while loop you
need to step through your array one spline at a time.
 Try This
#declare ArrayHairSystem = array[4] {
spline { cubic_spline
0/9 <1.104,-0.535,-0.7421>
1/9 <1.358,-0.4768,-0.8438>
2/9 <1.626,-0.3345,-0.922>
3/9 <1.939,-0.1466,-0.9378>
4/9 <2.328,0.04195,-0.8999>
5/9 <2.732,0.1853,-0.8488>
6/9 <3.079,0.2744,-0.8224>
7/9 <3.371,0.3472,-0.8292>
8/9 <3.616,0.4306,-0.8473>
},
spline { cubic_spline
