Apply the keratin only to the hair you want treated, then flat iron only that hair--or you can flat iron the rest as well, but I'd rather not subject the rest of my hair to the heat when not necessary.[/QUOTE]
How do you know where the stop flat ironing? How do you mark that link on your hair? I'm having trouble with this because when my hair is wet it is hard to remember where that line is on each small section.
