-- Mark-Paul Gosselaar first rose to fame as blonde-haired teen Zack Morris in the popular sitcom, "Saved By the Bell."
However, a lot of work went into making him look like that: He dyed his dark hair blonde for every episode.
"People go, 'Wow! You're not blonde anymore,'" Gosselaar said during an appearance on "Live with Kelly & Michael." "When was I ever blonde? That's not real!"
Gosselaar, 40, now starring in the TNT series "Franklin & Bash," said that while he's glad to have maintained a friendship with his former co-star Elizabeth Berkley, he's not sad that his constant trips to the hairdresser are done. In fact, he marvels that after "putting toxins on [my] hair for six years," that he hasn't gone bald.
"I can't believe I have hair now," he said. "I did that... [and] it wasn't natural."
