The methods for hair straightening are almost the same for both men and women. Hair straighten can either be done by visiting a beauty salon or DIY project. People usually go to the salon if they want to do a permanent straightening as it involves using chemical products to straighten the hair and the effect lasts longer. For temporary hair straightening, people prefer to straighten their hair at home by using a hair straightener. The cost for hair straightening differs from one beauty salon to another; it also depends on the thickness, length and type of the hair.
