There are many different treatments and processes to chemically straighten your hair
and some are harsher than others.
Usually a mix of chemicals is used to break down the bonds that hold the shape of your curls and heat is passed through the hair
to help oxidise the chemicals and keep hair
But as expert hairdresser Christian Toth says, the treatment isn't suitable for all types of hair
He says: "Extensively damaged hair
should not be treated."
A consultation with your hairdresser should be able to determine whether your hair
is suitable or not. If your hair can withstand it, then results can be blissfully long lasting.
Nathan Walker from Trebor Sorbie says: "The treated hair is permanently smoother and straighter as the hair grows the new hair will need to be treated - usually every three to six months."
