Who other than Halle Berry would be the best example of a gorgeous pixie cut. The pixie cut is in fact a classic and even the glamorous Audrey Hepburn favored this style. Again, like the crop - it is a huge transformation if you are going from long hair to the pixie. If you are proud of your facial features - a pixie cut will bring those features forward. Slightly wavy hair, an oval, heart-shaped or square face are the best matches for this short do.
Sedu hair basically means straightened hair that is sleek and soft in appearance. Katie Holmes probably uses straightening irons to make her short cut so silky. I for one envy the style of Katie Holmes which is classic, yet modern enough for the younger women. Her hair just makes me want to reach out and touch it - only I often found the computer screen got in the way. The Sedu can be flexible in that it suits most hair types. All you need is a good set of straightening irons and a little more patience if you hair is naturally curly.
