## Description

Majestic Hair BTX is the most advanced hair repair and straightening formula worldwide. The treatment repairs the damaged or broken hair fibers with a powerful concentrate of active ingredients which guarantee to moisturize, nourish, repair and revive hair right from the very first use, adding incredible shine and softness and eliminating frizz. Major benefit of the treatment is that it has the capability to repair split ends.DIRECTIONSWash the hair twice with Majestic Clarifying Shampoo. Rinse well and towel dry. For very tight curls & virgin hair, leave the Clarifying shampoo on for 10 minutes to ensure that the hair cuticles are ready to receive the treatment.Blow-dry hair with hair dryer with moderate heat to 80%.Part hair into 4 sections. Apply BTX Treatment with a color brush section by section 1/4 inch from root. Do not over saturate. Comb the solution throughout the hair entirely (the more the hair is brushed, the better the result).Leave the treatment for 50 minutes for wavy/frizzy hair and up to 75 minutes for very curly hair.Rinse hair thoroughly and completely with water.CAUTION: This step is different from all other Brazilian treatments. You first rinse the treatment from hair then you use the Flatiron. DO NOT use the flatiron before you rinse Treatment from hair.Blow-dry hair completely 100% using your hair straightening techniques Use Majestic Premium straightening iron at 440F/230C. Iron each section 4-7 times to properly seal the treatment into the hair cuticles. Iron very small portions of hair for best results.NOTE: For bleached blond hair reduce heat to 375F/180C. Adjust the heat by the hair condition.Maintain Treatment with Majestic Replenishing Shampoo and Conditioner every time you wash your hair.
