Depends on the type of the hair and the shape of the woman's face. If it is too round, the hair should be more straight to the shoulder, sometimes a short hair cut looks amazing, my sister has short hair and she has a beautiful face, other woman I know has long straight hair and she looks amazing too. I believe the best advice ever should come from a real hair professional, I think it worth to pay someone to decide with a woman what to do with her hair and then after she can just maintain it. I do not agree with the " What makes you feel good it is right", many times it is not true, some chubby women may feel terrific wearing a mini-skirt or a skinny jeans, but they will not look good at all and people will comment about the outfit,which is not okay. Same with the hair. Look for a expert in this case!
