I’m on the fence with the Keratin treatment. On the box it says to “rinse out”, then blow dry. But on website and Instagram, users said to use a fine tooth comb to remove excess product, do NOT rinse. I was confused and tried to reach them. All of their customer service numbers are bogus, or disconnected! Frustrating. I got a response like they had no idea what I was asking. The box instructions are opposite of what they are showing on social media. To me that’s pretty big confusion for the customer. I used the keratin, removed as much excess product as possible, then blew dry and ironed. My hair smells horrible, is much lighter, and feels so gritty. It does not feel or look shiny and straight. It’s straight, but very gritty and feels super dry. I don’t understand a company without good clear instructions, and no number to call to ask. Something is not right with my result. I’m hoping when I wash it tomorrow, it will feel better.
