The other major difference with the CHI Straightening System is the price. Price points for a standard chemical relaxer start at around $50 - $100. The CHI straightening system will be significantly higher. Most salons that I have spoken to start at around $300 - $500.
So, is it worth the extra cost? If having soft, straight, shiny, bouncy hair is important to you, then absolutely. It's important that you choose a stylist that is well versed in doing this type of service. Timing and following the steps of the service exactly are very important and, as with any chemical service, can have devastating results if not performed properly.
What kind of maintenance is required?
It's important to take good care of your hair after ANY chemical service, and the CHI straightening system is no exception. CHI recommends using Silk Infusion and Keratin Mist. A heat protecting spray should still be used when using a flat iron or curling iron (and it is okay to curl your hair after you straighten it). A good moisturizing shampoo and conditioner will keep your hair in good condition after the service as well.
