January Jones' Hair Color Changes Again As Actress Goes From Blonde To Brunette (PHOTOS)

First she was a blonde, then a redhead, then a blonde again and now ... a brunette!

January Jones debuted her darker 'do while out and about with her 1-year-old son Xander in Pasadena, Calif., today (Nov. 19).

All summer, Jones was sporting red locks, but soon returned to her blond color in September. She even tried out pink streaks earlier this year!

Now, it appears that the "Mad Men" star has dyed her hair brown -- and we love it.

The 34-year-old actress can obviously pull off any hair color, but what's her best shade?

See photos of January's ever-changing hair below:
