It looks like Selena Gomez has a little advice for her ex Justin Bieber, especially when it comes to his ever-evolving looks.

HollywoodLife.com is alleging that Gomez isn’t the biggest fans of Justin’s platinum blonde hair, which he showed off on Instagram earlier this week, and revealed that Selena is worried her ex’s world famous hair may be getting too damaged by his constant chopping, changing and dying.

“Selena is not crazy about Justin’s ponytail look. She thinks he has gorgeous hair, but is worried that it’s taking a beating with all the back and forth on his color changes,” a source allegedly told the site of Gomez’s feelings regarding Bieber’s ever-changing hair do’s.

“[Selena is] concerned his hair is going to eventually fry the next time he bleaches it. Selena’s advice to Justin is to go back to his natural hair color and let it be,” the source supposedly added.
