generally if u wanna create the volume effect on your
hair:
scoop up a considerable amount of wax/mud (slightly less than the
area of your thumbnail)
rub your hands together to spread the wax/mud evenly
apply the wax/mud onto your hair by messing up your hair (not too
much, just lightly)
proceed to style your hair to your desired style
______________________________________________________________
for the "spiky" effect:
repeat the same as above
twist and pull up areas of your hair which you wish to spike
