Katherine has great hair! That pretty much sums it all up.
I believe she may be wearing hair extensions for the added length.
When she went for the tryouts at American Idol, her hair was not
this long.
Hair extensions are probably the best way to get instant long hair.
But, be aware of the maintenance and extra styling time necessary to
keep these beautiful locks in tip top shape.
To create this straight and smooth long hair style, apply a
straightening cream
throughout the hair. Blow dry the hair using a large round
brush. Direct all ends and layers under.
Create the extra smooth finish by running a flat iron over all the
hair, from the roots to the ends. Spray a shine serum all over
the hair and you are done.
Some types of hair extensions, mainly synthetic
ones, cannot be styled using a curling iron or flat iron. Hot rollers are a
must or the hair will melt.
