1000ml 12% Pure Keratin Hair Straightening Treatment for Frizzy and Damaged Hair How to Use: Wash hair twice with purifying shampoo on chemically-treated hair, or three times on virgin hair. Blow dry hair completely until 100% dry. Shake the bottle well and pour approximately 2–3 oz of the Pure Keratin treatment into a bowl. Apply the treatment evenly to hair using a brush in 1/2-inch sections. Comb through each section thoroughly to ensure complete saturation. Wear gloves during application. Place hair under a processing cap. For chemically-treated or damaged hair, allow the treatment to process for 20 minutes, then blow dry hair completely. For resistant or coarse hair, allow the treatment to process for 30 minutes, then blow dry hair completely. Using a heat-resistant comb, divide hair into four sections. Use a flat iron set at 450°F (230°C). Starting at the nape of the neck, work in 1/8-inch sections, passing the iron from root to ends 5–7 times. For extremely curly or coarse hair, pass the iron 7–10 times to fully infuse the keratin into the hair shaft. For chemically treated or damaged hair, reduce the iron temperature to 430°F. Wait 72 hours before washing hair. After this period, cleanse with sulfate-free shampoo and conditioner. Package Includes: 1 x 1000ml Pure Keratin Treatment
