Generally speaking, if you want less volume go for long layers. If you go for one-length but have dense hair you may end up with the "triangle-head" look. I used to have that problem when I had higher density. Now that my hair has thinned , I got it cut to shorter layers and it works MUCH better. My hair looks fuller now.
fine - low/normal porosity - medium density - normal elasticity.
