It took roughly two hours in my instance. Coppola Keratin claims to remove frizz and loosen curls. The Brazilian Blowout takes significantly longer, but in exchange for additional chair time, I was allowed to wash my hair right away. The Brazilian Blowout contains extra phases, which lengthens and complicates the procedure. There's also a risk of infection since they use instruments on your head. The cost of the Brazilian Blowout varies by practitioner and location. An average price in the United States is $450-500. In Brazil, it's $120-150. That's why people go to celebrities; they want the same result but can afford their price. The number one reason why people have hair transplants is because of their price tag. It's not easy to find a qualified surgeon who operates at reasonable rates. There are many more reasons to have a hair transplant than just cost. For example, a coppola keratin treatment isn't enough to fix dry, damaged hair. You would need several treatments over time to achieve that goal. With a Brazilian Blowout, you will get all natural-looking hair that grows back white or brown depending on the color of your skin. Not only that, but also your new hair style will stay for up to ten years! The main difference between a Brazilian Blowout and a coppola keratin treatment is length of service and cost.
