Growing out relaxers

Does anyone have any tips for growing out relaxers without having to cut the hair short? I am at a point in my life where I am tired of having to run to the hair dresser every few weeks. Can I hot press the roots while they grow out? I am also hesitant to use the 'Flat Out'/no frizz products. They say that 'they become more effective over time'. Is this because they are actually permanently relaxing the hair in some way? I started to use on my eleven year old daughter's virgin hair but stopped because I did not want to change the texture of her hair entirely.Any thoughts are appreciated. Regards.
