Marcy McKenna, 44, from California, was fed up with beauty products cluttering her bathroom then she noticed her seven-year-old son, Jack, playing with his LEGO bricks.
The mum jokingly challenged him to build a box out of LEGO for her. Jack then worked with his mum and grandmother to figure out where each of her styling tools would go, and how the cords would be stored. Marcy was so impressed with Jack's attempt that she turned the prototype into a working device.
After hurdling many obstacles, the $132 'Huffington Post that her husband often complained about the styling products and tools she would leave lying around.
She said: "Almost every morning [he] would make some sort of comment about the hairdryer I had tucked into a towel bar or a styling iron I'd left out to cool on a counter top.
"There were electrical cords everywhere. And it wasn't just our bathroom.
"My mother lives with us and because we have a pedestal sink in the bathroom she uses, she was storing her styling tools in a big white bucket. There was just nowhere to hide the mess."
As she discussed her clutter issues with her mother, she noticed that her son was sat playing with his LEGO and asked him for help.
She recalled: "I thought, if this turns into something, I'm always going to remember this moment."
Getting the product to market was no easy feat so Marcy entered TLC's contest, Homemade Millionaire. The reality show arms inventors with professional product guidance and exposure to suitable distributors.
After competing as one of only three finalists in the beauty product category, Marcy's Style & Go was declared the winner.
The device made its debut on shopping networks including QVC and HSN in the summer of 2012, and was then snapped up by one of America's biggest stores.
Marcy now projects revenue of nearly a million dollars.
