Fans were quick to share their thoughts on the procedure.
"I thought you had good hair?!" one questioned, to which Daniel replied: "It was okay but years of steroid abuse did permanent damage and I had the opportunity to improve it so why not?"
"No one’s hair line is that straight???" another added. The star responded: "Mine is."
A third penned: "You were handsome before. You will be more handsome now 😍."
While the couple hit it off on the show and even stayed together after filming had wrapped, they eventually parted ways in August.
"I'm getting bombarded so much at the moment considering all the articles out right now about the status of Carolina and I," Daniel wrote in a statement.

"I think it's been obvious for a while we have gone our separate ways. There's no right way to deal with these situations," he continued.
"There's a huge pressure to just hold off going public for as long as possible cause you know all the hate that's gonna come.
"I wish Carolina all the best and I know she feels the same for me, we had a very unique experience together full of every emotion possible but life just has a different plan for us."
The announcement came just hours after Daniel's close friend, and fellow MAFS alum, Jackson Lonie confirmed his split from Olivia Frazer in a joint statement.
"There has always been a lot of love in our relationship and there will continue to be as we transition into a friendship, the pair wrote.
"We have nothing but love and respect for one another, and no one is to blame for the end of this relationship. Simply a case of 'almost perfect'."
