Be aware that the majority of these photos were taken professionally, and hours of styling and preparation went into that style. This is not to say you shouldn't love the style, just remember that your hair may not look like that every day if you are not able or willing to put the effort into styling it. Your hairdresser can give you the exact haircut you asked for, but if you don't style it and use the proper tools and products, you are going to be very disappointed.
Almost every single person with long or full hair that you see on TV or in the press is wearing hair extensions. It affects the look of the cut and also the color. A photo of someone wearing extensions is not going to translate to most of us out there with fine hair. Out of all my clients over the years, I can count on one hand how many have that amazing, thick, shiny long hair. I call them my Barbies. They are the lucky ones, and very much the minority. Long hair looks good only on this type of hair. This is not to say that you couldn't or shouldn't consider hair extensions. I think that is a wonderful and fun thing to try. Just be aware that most of what you are seeing out there is a lie. They have a secret, and it is hair extensions.
I do not want this to discourage you. I just see so many people who really think these looks can be carbon copied. It is just not realistic. Be aware, and change how you look at these inspirational photos. Take several to your next appointment, and go through them with your hairdresser. I am willing to bet that you will come out with a good happy medium that is your best hairstyle
