In my opinion, long hair only looks great if it's nice and healthy. However, it is only natural to get attached to length of your hair, especially when it's past the shoulders, but it doesn't necessarily mean it looks good. A great hair stylist will tell you his/her professional opinion on:
1. What lengths will look good on you
2. How much to cut off in order for it to look it's best health wise
Cutting the right amount of layers, length, and of course texture are the three major key points in a long haircut. Without the correct balance of all three, it simply won't live up to its full potential; this is why the most important thing is to do your research on hairstylists, because once you choose one who works for you, trust their words because it's a team effort to get your hair long.
Make sure you don't go six months to a year without getting a haircut... sometimes a great haircut can hold its shape for several months, but for the most part, I recommend trims or reshaping every eight weeks. Most of you are probably thinking ‘why cut my hair if I'm trying to grow it?’ well, split ends tend to follow up the hair shaft towards the scalp... the longer you leave them, the higher up they will split and the more length you will have to get cut off.
A good stylist on a set schedule can have your hair looking its best throughout the year while growing it out flawlessly. This way your end result is going to be healthy, long sexy hair.
Once your hair is at a length that you're happy with, ask your stylist to add face framing layers that will bring out the best in your face shape. For Kim lately we've been keeping her shortest layers around her lips so that it opens up her face from all the length and shows off her amazing cheek bones and pout.
