Is Cameron played by the same person in all the episodes including the pilot?

Yes. Jennifer Morrison has always been Cameron on the show, but she was a brunette until season four, when she dyed her hair blonde.

Yes, she is the exact same person. I laugh at your stupidity I really do.

And for the record, JM is a natural blonde anyway. She had highlights in season 3 not a full colour change. So she hasn't technically changed her colour in all three seasons.

Explain to your friend that maybe he/she is confusing cameron with 13. JMo always plays Cameron.

Yes Jennifer has her played throughout the entire series. She was a brunette at first and then she dyed her hair blonde.

Jennifer Morrison seems to change her hair color every season..

She has always been the same person. Now, some episodes she doesn't show up, but her character has always been played by Jennifer Morrison.

Jennifer morrison as always been Cameron...... and i wouldnt have it any other way
