IQ Natural Brazilian Keratin Complex Hair Straight Guard System
This three-part Brazilian keratin straightening system contains keratin shampoo, conditioner, and smoothing treatment for optimum straightening results. The pure keratin protein is in a liquid form, allowing it to permeate your hair follicles and force them into a more manageable state. Most users agree this system is effective at making hair smooth, shiny, and less frizzy. Hair becomes more manageable, if not straighter, and results last approximately three to four weeks. This system may not work as well on thick or coarse hair, though.
