Hello,
I read in other parts of the website that the Tutanat Brazilian therapy uses cysteine and in other parts I read that it uses keratin. Does it use cysteine or keratin to straighten the hair? Also, are any of the products formaldehyde free? I really would love to try your products but I am concerned about the formaldehyde content.
Thanks,
Joyce.
