LOS ANGELES,

Jada Pinkett Smith turned her husband’s Oscar-night blowup into a teachable moment about alopecia areata, the hair-loss disorder affecting her and millions of others that, in some cases, can impact a person’s sense of identity.

“Considering what I’ve been through with my own health and what happened at the Oscars, thousands have reached out to me with their stories,” Pinkett Smith said on Wednesday’s episode of “Red Table Talk.”

The actor said she chose to use “this moment to give our alopecia family an opportunity to talk about what it’s like to have this condition” and what it is. Her guests included the mother of a 12-year-old girl, Rio Allred, who was bullied over her hair loss and died by suicide, and a physician who explained the different types of the disorder.

Before tackling the subject, Pinkett Smith addressed events at the March 27 Academy Awards. She and husband Will Smith, a best-actor nominee, were in the audience as presenter Chris Rock cracked a joke at Pinkett Smith’s expense.

“Jada, I love you. ‘G.I. Jane 2,’ can’t wait to see it,” Rock said. Pinkett Smith, who has spoken publicly about her alopecia, had a closely shaved head similar to that of Demi Moore in the 1997 movie.
