About ThatGirl

Confidence. Fullness. Quality.

That’s the heart of ThatGirl Hair Extensions — and the vision of founder Katie Morgan.

I’m Katie, an upstate New York–based hairstylist specializing in custom blonding and extensions. I’ve spent years behind the chair helping women transform their hair and confidence. But I wanted to create something more — a line of extensions that gave clients salon-quality results at a price they could feel good about.

ThatGirl isn’t just a company.
It’s me, it’s you, it’s every woman who wants to walk into a room and turn heads.

 

Why I Started ThatGirl

After years of working with extensions from different brands, I saw the gaps — hair that didn’t last, colors that didn’t blend, and prices that didn’t make sense. I worked closely with my supplier to source 100% Remy human hair from Russia, known for its unmatched cuticle alignment, fullness, and silky texture.

I hand-select, test, and approve every product before it’s offered to you. Whether it’s Genius Wefts for a long-lasting salon install or Seamless Clip-Ins for instant at-home glam, every strand is chosen with care.

 

My Promise to You

When you shop ThatGirl, you’re not buying from a corporation — you’re buying directly from the stylist who will happily answer your questions, color match your order, and guide you on how to care for your hair so it lasts.

This isn’t just hair.
It’s confidence you can wear.
