Why "That Girl" Culture on TikTok Is Both Inspiring and Dangerous for Teen Girls

By Ka'Cheena  ·  Becoming Her Within

If you've spent any time on TikTok lately you've seen her.

She's up at 5AM. Green juice in hand. Journaling before sunrise. Working out before most people have hit snooze. Skin glowing. Outfit perfectly curated. Life seemingly together in every possible way.

She is "That Girl." And millions of teen girls are watching her — and measuring themselves against her — every single day.

Here's what nobody is talking about.

You're only seeing a snippet.

The thing about social media is that it shows you someone's highlight reel and lets your brain fill in the rest. You see the 5AM workout and assume everything else in that person's life is equally put together. You see the glowing skin and the aesthetic morning routine and think — that's what having your life together looks like.

But you're not seeing the full picture.

You're not seeing the mental health struggles behind the camera. You're not seeing the creator crying over comments at midnight. You're not seeing the self doubt, the pressure to keep performing, the exhaustion of maintaining an image that was never fully real to begin with.

"Teen girls are consuming these snippets and building entire belief systems around them. When their real life doesn't match the highlight reel, they don't think 'that's not realistic.' They think something is wrong with them."

That's the danger.

The "That Girl" myth is not one size fits all.

Here's what I want every teen girl to understand — and every adult supporting them.

"That Girl" looks different for everybody.

For some people waking up at 5AM is genuinely energizing. For others 7AM works just fine. For some girls a full skincare routine is grounding and joyful. For others it's overwhelming and unnecessary. The version of your best self that works for you is not going to look like the version that works for the girl on your For You page.

I don't wake up at 5AM. I wake up at 7. I do my makeup, get my hair together, work out, get myself organized, and I'm out the door by 8. That works for me. It took time to figure that out — and it didn't come from watching someone else's morning routine. It came from paying attention to myself.

That's the part TikTok leaves out. The figuring out. The trial and error. The permission to do what actually works for you instead of what looks good on camera.

Start small. Seriously.

One of the most powerful things I've taken from my own growth journey — and something I bring directly into my work with teen girls — is the concept of starting small.

You don't have to overhaul your entire life to become your best self. You don't have to add five new habits before breakfast. You don't have to do everything at once.

"Pick one thing. Work that one habit consistently for months before you add anything new. Real growth is slow. Real growth is small. Real growth is sustainable."

Want to journal every day? Start with journaling. You don't have to wake up at 5AM, journal, meditate, work out, meal prep, and manifest before 10AM. That doesn't make you "That Girl." It exhausts you. And an exhausted girl who burned out trying to keep up with a TikTok trend is not going to stick with any of it.

The part "That Girl" culture gets completely wrong.

Here's what bothers me most about the way "That Girl" content reaches teen girls.

It prioritizes the outside over the inside.

Lashes. Lipstick. Aesthetic workout sets. A perfectly organized desk. These things are not bad. Aesthetics are not the enemy. But aesthetics alone will never make you feel like her.

"Anybody can do their makeup. Anybody can buy nice clothes. But if you don't feel good about yourself on the inside — none of that is going to fill the gap. Who are you doing it for? Yourself? Or for people watching?"

That is the question I ask the girls I work with. And it's a question more teen girls need to sit with before they build their entire identity around a trend.

What "That Girl" energy looks like when it's healthy.

Here's the thing — the desire to be your best self is not the problem. That desire is actually beautiful. It means something in you is reaching for growth. That's worth honoring.

The problem is when that desire gets hijacked by comparison, by unrealistic standards, and by the idea that there is only one way to show up as your best self.

In Becoming Her Within we redirect that energy. We help girls ask — what does YOUR best self actually look like? Not the TikTok version. Not the influencer version. Yours. What habits make YOU feel good? What routines feel sustainable for YOUR life? What does confidence feel like in YOUR body?

That's the work. And it's so much more powerful than any 5AM morning routine.

What parents and educators can do.

If you have a teen girl in your life who is deep in "That Girl" TikTok culture, the worst thing you can do is dismiss it or take her phone away. That energy — that desire to grow and improve — is worth engaging with.

Instead, ask her questions. What about that content resonates with her? What does she actually want to feel like? What's one small thing she could start with that feels genuinely good to her — not performative, not for the camera, just for herself?

Help her build a relationship with her own instincts. That skill will serve her long after the trend has moved on.

Ready to help the girls in your life build confidence from the inside out?
