NAAT Brazilian Keratin Liquid Keratin Leave-In Reconstructor
The NAAT Brazilian Keratin Liquid Keratin Leave-In Reconstructor is a leave in – non-rinse formula. Apply desired amount to freshly shampooed and conditioned hair. Wait a few minutes before blow drying as usual, and feel the results immediately. The leave-in is activated by the blow-dryer and a flat iron will seal hair cuticles causing keratin to effectively penetrate hair fibers. Designed for frequent use or as needed.
