Hi everyone! After reading this whole thread and doing a ton of research, I finally decided to take the plunge and get a BKT last week. I went to a stylist who had done a BKT on a coworker. She used the Coppola brand. At first I was like, what have I done to my hair, but a little over a week later I could not be happier with the results. Here a are a few pics.
Here is my hair after the clarifying wash:
After washing, she blew dry, applied the keratin, let it sit for 30 minutes, blew dry again, then flat ironed. Here is my hair after the flat iron: (ETA: I forgot to say that she also had to trim about a half an inch or so all over due to my ends being a little raggedy.)
I then had the three day wait. During this three days was when I was having second thoughts about what I had done to my hair. I thought it looked limp and I was so scared it wouldn't curl back up. Luckily I had nothing to worry about!
Here is my hair after returning to the salon three days later. Washed, flat ironed, and styled:
And here is my hair today, a week and two days later, in a wash n go.
As I said, I was thrilled with how it turned out. My hair feels so soft and moisturized, my curls are a bit looser, and drying time is so much faster. I haven't flat ironed it myself yet but I'm sure that will be a breeze too. My hair also feels much stronger.
I want to make sure that I don't lose my curls, so I don't think I would get this done too often. Twice a year was recommended to me so that the keratin doesn't build up on my hair too much.
The only regret I have is not getting my color touched up before the BKT. I was too impatient. I was told by the stylist that I would have to wait a month or so to have my color done.
