Comb ur hair into a ';bird's nest'; and tie ur hair in a scarf at night. When u do this, relaxers last longer, and u should b able 2 get away with ironing ur hair a MAX of 4x's a week.How to extend your relaxer without killing your hair?
You can try wrapping it at night, tie with a scarf and in the morning comb it out. It helps to keep the hair flat and straight without having to re-flat iron it every day.
