As Bruce Jenner prepares to complete a life-changing transition, he can count former stepdaughter Khloé Kardashian among his cheerleaders.

Sunday’s episode of Keeping Up with the Kardashians opened with a brief discussion about Jenner’s changing looks as Khloé examined one of the first photos of Jenner with noticeably longer and fuller hair.

“So, Bruce’s hair looks different,” Khloé prompted sisters Kim and Kourtney, as well as Kourtney’s partner Scott Disick.

Disick called Jenner “The Extensionator,” but Khloé insisted it was his real hair. “I just think it looks really good now,” she said, to some skepticism from Kim. “Really good?” Kim asked. (Maybe she’s remembering the time Bruce called her sloppy bun a "look.")

“It looks thick!” Khloé maintained. “It’s thick and lustrous!”

Though the conversation then turned to Kourtney’s upcoming nude photo shoot, this coming week will have plenty of talk of Jenner for those interested in his transition from male to female.

His 20/20 interview with Diane Sawyer airs Friday, in which Jenner, 65, will speak publicly for the first time about his journey.

“Bruce’s primary goal is to bring awareness to this issue in order to help others in the transgender community,” a source told PEOPLE in March. He “wants this to be taken seriously so that [his situation] can have the most positive impact on society’s perception of the transgender community.”

Keeping Up with the Kardashians airs Sundays (9 p.m. ET) on E!
