Mix in full contents of developer bottle. Stir until the mixture is a smooth consistency and there are no lumps. *If you are only doing your roots and/or do not require as much product, mix one-part bleach to two parts developer. Use a scale for accuracy. For example, 1oz of bleach would be mixed with 2oz of developer. APPLICATION: 1. Wear included gloves and cover clothing. Start with dry, un-shampooed and detangled hair. Start at the crown of the head and work in small sections. Finish your roots last, as they tend to lift faster. 2.Using a hair applicator brush, fully saturate each section, working the bleach down the hair. Leave the roots for the last step, as they will lift quicker. 3. After all sections are fully saturated go back and apply bleach to your roots* and any missed spots. 4. Wait 30-45 min paying close attention to the condition of your hair while processing. Check every 10 min. To check the process, wipe excess product from a small of piece of hair using your gloved hand. If the hair is not lightened enough, leave mixture on longer. DO NOT leave on for more than 45 minutes 5. Rinse hair thoroughly with lukewarm water, ensuring that all product is washed out. *If you are only bleaching your roots, do not apply over previously bleached hair. Overlapping could cause excessive damage to hair. Read all directions and warnings before application. Perform a skin allergy test 48 hours before each use of KERACANVAS, as allergies can develop suddenly, even though you have previously used this product or similar products from other brands in the past. * Do not use if you have sensitive, itchy or damaged scalp.* Avoid contact with skin and eyes.* Do not get mixture in eyes; to do so may cause blindness.
