Djoulisa Allen
Djoulisa Allen is the founder and creator of HairGrid. As a Black woman who styles her own hair, she spent years navigating the same frustration millions of women know too well: there was no reliable way to see the back of her head while styling.
The two-mirror juggle. The phone propped against a wall. The uneven parts discovered only after hours of work. She knew there had to be a better way.
Rather than wait for someone else to build it, she created HairGrid — a purpose-built tool designed specifically for the way Black women care for their hair.
What HairGrid Does
HairGrid streams a live rear camera view from your phone to your laptop screen, with an adjustable precision grid overlay. It gives you a clear, hands-free view of the back of your head while you style.
The grid helps you part evenly, section consistently, and replicate styles that worked. Session history lets you track your progress over time.
All you need is an iPhone, a laptop, and a phone stand. Both devices connect wirelessly over the same Wi-Fi network. No special equipment, no complicated setup.
