I spend most of my days buried in code, algorithms, and theory. My world is made up of models, data, and performance metrics. But every now and then, I come across an innovation that reminds me why I fell in love with artificial intelligence in the first place.
Something that feels human.
That’s exactly how I felt when I discovered Halo Braid—a startup that’s teaching robots how to braid hair. Yes, you read that right. A hair-braiding robot.
But it’s not just a cool gadget. It’s a powerful story of culture meeting technology.
The Problem We All Know (But Few Have Tried to Solve)
If you’re a Black woman—or part of the African diaspora—you already know the ritual. Sitting in a chair for six hours. Paying up to $300. And for the stylist, enduring pain and strain that can lead to arthritis before the age of 30.
Braiding is an ancient art form. It’s part of who we are. It connects generations. Yet, as Halo Braid co-founder Yinka Ogunbiyi pointed out in her winning pitch at the Harvard Innovation Labs, this practice hasn’t seen any real innovation in over 5,000 years.
Until now.
The Birth of Halo Braid
Halo Braid was co-founded by Yinka Ogunbiyi and David Afolabi, two visionaries from Harvard Business School. Their invention—a patent-pending robotic device—just won the 2025 President’s Innovation Challenge.
Here’s what makes it brilliant: the robot doesn’t replace stylists. It works with them.
The stylist starts the braid, and the robot finishes it. This collaboration allows stylists to take on more clients, grow their income, and save their hands from injury.
Ogunbiyi calls it “a way to grow your business without destroying your body.”
That’s empathy-driven design. And that’s what makes this so powerful.

Where the AI Magic Comes In
Now, let’s talk about the part that lights up my researcher brain—the machine learning.
Braiding isn’t like assembling factory parts. Every head of hair is unique—texture, thickness, and curl pattern. There’s no one-size-fits-all algorithm for that.
To achieve professional quality, Halo Braid had to build a system that can see, learn, and adapt.
It uses computer vision to analyze the hair and ensure consistency.
It relies on sensors to detect tension and grip, so it doesn’t pull or break strands.
And it’s trained through reinforcement learning, meaning it gets better with every braid it completes.
According to Ogunbiyi, the robot has already completed thousands of braids—and it’s now able to braid five times faster than a human stylist.
That’s not just AI for efficiency. That’s AI that understands texture, culture, and care.
Why It Matters
Halo Braid isn’t just a tech story. It’s an empowerment story.
1. Economic Empowerment:
Stylists, especially Black women, can now scale their businesses. What used to take six hours can take a fraction of that time, allowing more clients, more income, and more opportunity.
2. Health and Well-being:
This technology directly addresses the physical toll of braiding—chronic pain, arthritis, and exhaustion. It protects the hands that have carried a cultural art form for centuries.
3. Cultural Continuity:
And maybe most importantly, it keeps braiding joyfully. It preserves an ancient tradition while removing the pain and fatigue that often come with it.
AI in Service of Humanity
Too often, AI feels distant—abstract models solving abstract problems. Halo Braid flips that narrative.
This is AI that touches real lives. It honors culture. It uplifts the people it serves.
And that’s the kind of innovation I want to see more of across Africa and beyond — not just AI for efficiency or scale, but AI that understands our context, our struggles, and our stories.
Because when we build technology that’s rooted in empathy and culture, we’re not just making machines smarter. We’re making humanity stronger.
Halo Braid is proof that AI doesn’t have to live in the clouds. It can live in the salon, in the marketplace, and in the hands of everyday people.
That’s what excites me most as an AI researcher—seeing intelligence, both human and artificial, come together to create something beautiful.
Something that finally says: this is for us.
