Barrois was trained by Patrick Schmidt, and later by Andreas Spaniol, and her stamina-trainer was the footballer Bernd Franke.

On 14 December 2008, she won her second German Tennis Championship, with a win in the final against the unseeded Lydia Steinbach.

She also reached the first round of the Australian Open, where she pushed the fourth-seeded Russian Elena Dementieva, but eventually lost in three sets.

In March, she played an ITF event where she lost in the quarterfinals to British player Katie O'Brien.

She qualified for her first ever final in a WTA tournament, the Internationaux de Strasbourg,[1] which Maria Sharapova won in straight sets.

After losing to Lucie Hradecká at the Luxembourg Open in October 2014, Barrois announced her retirement from professional tennis.
