Hair straightening, also known as relaxing, is the opposite of perming! You can straighten your hair chemically or you can do it with products that temporarily tame the curls.
The main reason that people decide to have their hair straightened is to eliminate curls. Hair straightening should always be performed by a hair salon professional.
Fine, lightened or colored hair requires a very mild relaxing formula. Normal, medium-textured hair requires regular strength relaxers.
Coarse hair requires a strong or super relaxing formula.
