Not to mention your hair will style easier. What happens to your hair when you color it with dye that has ammonia? The ammonia relaxes and lifts the cuticle to enter the cortex. The problem really is that, in the same process, it causes the hair to lose protein and become dehydrated. That is why many of us have noticed our dry, fragile, porous hair with frizz or with split ends after this procedure. How does Neala Dye work if it is ammonia free? It acts via PH adjustment. The adjustment of PH is done with our unique formula of oils, aloe, and alcohols that open the hair cuticle gently allowing the hair to be permanently colored. DirectionsMix with peroxide at the ratio of 1:1. Process on normal hair for 30 minutes and coarse resistant hair for 45 minutes. For high lift color (level 12) mixing ration 1:2 and process for 45 minutes. To get maximum 100% gray coverage mix a minimum of 50% Natural or Warm Natural in your formula with your desired shade. For example: To achieve a tone of 6.44, a mixture of 1oz 6.07, 1oz 6.44, and 2oz 20 volume peroxide. Process at room temperature.
