Prepare Color_Treated Hair for Hot Tool Usage with Heat_Protecting Products : If you use blow dryers and irons on your hair, make sure that the hair is completely dry before using heat so it won’t cook from the inside out. Prepare the hair with a fortifying leave_in conditioner and finish with a protective hairspray. Maintain a Healthy Diet to Keep Your Hair Looking Great : What you eat has everything to do with the health of your hair, and how it looks. The nutrients from a healthy diet provide the energy that fuels hair growth and luster. Foods that include iron_rich protein feed your scalp and hair by building strong keratin, the protein that strengthens hair, improves texture and stimulates growth. Consume lean meat, fish, low_fat cheeses, egg whites, spinach and soy to keep your color_treated hair looking its best. Between meals, snack on fruits, nuts, vegetables and grains.
You must condition when you're done. "If you skip the conditioner step, it leaves the cuticle open and the color keeps working," says Ionato. "So don't be surprised if you end up with much darker hair than you wanted." Don't throw away the conditioner in the kit, and if you do, make sure to use a deep conditioner in the shower after you rinse out the dye.
