As previously shown on Married at First Sight's seventh season, Dave's type happens to be a tall brunette, with his celebrity crush being Jessica Biel. Amber was already feeling insecure about her looks, and then Dave seemed to suggest she should stop dying her hair platinum blonde over dinner one night.
"I'm starting to lose my hair... I think I might be dying it too much," Amber said in a recent episode.
"Maybe women everywhere are going to hate me for saying this, but if it's truly making her hair fall out, just stop doing it. It just doesn't seem complicated to me," Dave told the cameras, before asking Amber to stop.
Amber then nipped their conversation in the bud because she felt Dave was trying to talk her into having darker hair.
During an appearance on Tuesday night'sMarried at First Sight: Unfiltered with his co-star Bobby Dodd, a fan wrote Dave the following question: "Do you actually want Amber to dye her hair brown and is this your way of telling her?"
Dave elaborated, "I mean, obviously I had plenty of issues through this as well, but I think that was a little unfair. I'm just saying, 'Hey, I want you to be healthy,' and she's hearing, 'I want you to change your hair color.' That wasn't what it was."
Dave admitted he didn't catch on to the fact Amber had an insecurity about her hair color at the time.
"You know what's tough? I don't think in the moment I did. I didn't get what was going on. I didn't get why it was an issue. So what I should have done was -- rather than being sympathetic, I got frustrated," Dave reasoned.
Jamie then jokingly asked the guys whether they'd "rock a man bun" if that look happened to be their wives' type.
"No, I wouldn't rock a man bun," Bobby said with a laugh. "I really like Danielle, but I'm pretty sure she can do without a man bun."
