Permanent Hair Straightening is a permanent process. Permanent as in, your hair will stay straight until it is either cut off or it is permed again. Hair straightening is a hair styling technique which involves the flattening and straightening of hair in order to give it a soft, shiny, smooth and 'sleek' appearance. It may be accomplished by using hair irons and hot combs or chemical relaxers. In addition, some shampoos, and conditioners and hair gels, can be a help to make hair temporarily straight. Some color their hair to add flair and some for covering the gray hair. It is the quickest and most easy way to change your look.
