Like everything else, the older we get, everything starts changing. I always tell my clients, 'You have to work on proportion and volume and layers." When you're younger, you can get away with tousled, more messy looks. When you reach a certain age, you want to control it a little bit more. You can still have that idea, but it's very important to have more control.
With length, [when you're younger] you can get away with having it extremely long. As you age, you can keep the long hair, but the proportion should be right for the time.
Everything that completely puts together the right look for you should be a factor. The color is very important. The older you get, you have to maintain the look. Don't hope at 40 or 50 you can have the same look you would have worn at 20. You can have the same idea, but the proportion should be a little bit different.
