She displayed some classic bipolar symptoms, including erratic, reckless behavior, racing speech, grandiose ideas, hypersexuality, lack of sleep, euphoria and confusion . As often happens during manic phases, Silver ended up making destructive decision, which ended with her at the train station, rambling and bewildered, running toward a speeding train . It was confirmed in the following episode as she was diagnosed with the disorder . Silver's bipolar disorder was revisited after Adrianna tampers with her medication when implementing her plot for revenge . </P> <P> In Season 1, Silver is shown to have long black hair and dazzling blue eyes . She has a chilled, laid - back personality and seems to show disdain towards proms and school dances . She seemed to have her own sense of style, as she is usually seen wearing clothes probably would not be worn by a typical Beverly Hills girl . In Season 2, her hair was cut short and her sense of fashion has become more girly due to Naomi and Adrianna's influence but still remains her original style . Also, her interest in school dances seemed to have grown since she was seen going to the Snowflake Dance in "Winter Wonderland and the Pass the Torch Dance in "Confessions ." In Season 3, Silver's hair was styled like a tomboy's cut and dyed chocolate brown . For a short time in Season 3, while she was having another episode with her bipolar disorder, she dyed her hair an intense orange color in order to give it more "pizazz ." Eventually, she recolored it brown after returning from the psych ward . In Season 4, Silver's hair had grown into a style such as her former one in Season 2 but with blonde highlights . By the fifth season, her hair resembles her former self in Season 1, with her hair now below her shoulders . </P>
