I have noticed that styling short hair is an art, completely different than styling other hair lengths. It has to be molded a certain way and the cut is extremely important in getting the hair to lay properly.
I have also noticed that many people with shorter hair, over-process their hair. You still want it to be healthy. Dry and brittle hair doesn't look good at any length. The same hair care needs are imperative on all hair types and lengths.
I'm not the best 'yet' in styling short hair but I'm happy with my progression.
