Halle Berry has revealed why the back of her daughter's head is bald. The 53-year-old actress explained the reason on The Tonight Show Starring Jimmy Fallon.

Nahla, Berry's pre-teen daughter, found herself in a hairy situation after spending some time in the family's pool and neglecting to brush her hair afterward.

Berry said her daughter usually likes to handle her coils independently.

"My daughter's 12 and so every time I go to comb her hair, she's like no, don't touch me I can handle it, I'm a tween," the actress shared. I don't need you to brush my hair." 

Eventually noticing something different about her hair following the daily swim sessions amid social distancing, the girl went to her mom one night and said, "mom, I'm scared to tell you this, but touch the back of my head."

Berry then realized that her daughter's hair "has shrunken up into a tight ball that feels like matted fur."

  

"I can't even get my finger in it," Berry told Jimmy Fallon. "She's screaming so I said 'Honey oh God, oh God' and I'm trying to stay calm."

The Academy Award winner said she used conditioner to attempt to detangle the hair, but that only made the situation worse.

With Nahla's hair becoming tighter, the actress said she had to shave the back of her daughter’s head. The stunned Fallon asked if the girl was cool with shaving her head.

"She was not cool with that," the actress said. "But it was our only option."

Berry hopes her daughter learned a lesson from the messy situation. 

"But now she gets it. I was like 'first of all, maybe you'll let your mother help you,'" the Hollywood icon said. "Second of all, you've learned you gotta brush your hair, dawg, like every day. You gotta brush your hair."

Even during quarantine, Nahla learned that she has to take care of her hair.

"She's like 'we're in quarantine, we're not going anywhere. Why did I have to brush my hair?' I said 'this is why you have to brush your hair,'" the actress said.

Berry also told Fallon about a project she was working on before the coronavirus put everything on pause. The actress was set to make her directorial debut for a movie titled Bruised, but the outbreak has disrupted the schedule for the premiere. 

"It was supposed to come out in the fall this year, but now with everything that's happening, I think most productions are sort of in flux right now," she said. "The good news is that at least we finished it pretty much, so we have it kind of in the can. But … I don't know when we will get back to the movies and … life will get back to normal."
