This procedure has changed and improved greatly in the last few years. Through enhancements in products, and in the knowledge of structures and procedures, we can now offer you a great chemical straightening service. Your hair will be left straight and shiny and will last that way for about 7 months, depending on the individual. This is a complex job that takes 4 to 5 hours, but you will save an enormous amount of time over the life of the procedure by seldom needing to iron your hair. We do not recommend chemical straightening for highly coloured or bleached hair.
