When Lori was on FH, her hair was brunette, yet lately, it has been a lighter color. When did she change her hair color?

I'm not sure. She deffinitly changed her hair alot on FH. In season 2 it was brown. Then in seasons 3 and 4, it was amore blonde- brown. For seasons 5-8 it was sort of red. Also at the end of season 7, her hair was very dark, almost black.
