I did keratin 2 weeks ago. The master applied the composition without indentation from the scalp. As a result, she burned my scalp. I have already gone for peels several times to remove these flakes of skin. Not once in the many years that I have been doing these procedures has Pen had such a thing. The hair lies without a basal volume. The master didn't even ask how I wanted it, but I was sure it was obvious. After all, pen has no hair density.
Disappointed.
