Life, Money & Love with Dylan Mullan “$1,000,000 in 6 months!” - How a Hairdresser & Tradie created Australia’s most Viral Haircare HACK! (Coastal GRL)
Meet Sarah and Luke, the powerhouse couple behind Coastal GRL, one of Australia’s fastest-growing haircare brands. In just six months, they went from an idea in a small apartment to selling over 15,000 units and earning more than $1 million in revenue.
What started as a simple solution to protect hair from saltwater and chlorine has now become a movement - a brand built on passion, belief, and a whole lot of hustle.
In this episode, Sarah and Luke share how they turned a personal frustration into a viral success story. From late nights packing boxes and driving across the country to meet manufacturers, to seeing their products sell out faster than they could restock, their journey is nothing short of amazing.
In this episode:
- How Sarah turned a simple haircare frustration into a million-dollar business idea that changed her life forever.
- The bold $5K risk they took before even having a final product — and how that one decision sparked Coastal GRL’s explosive growth.
- Luke’s leap from tradie to entrepreneur and the mindset shift that made him an unstoppable business partner.
- The moment they sold 15,000 units in six months and realised they had built something far bigger than they ever dreamed.
- The emotional rollercoaster of starting a business as a couple — and how they learned to separate love from logistics.
- Why Sarah’s background as a hairdresser gave her the insight big beauty brands completely missed.
- How sending simple voice notes to customers turned angry complaints into loyal superfans.
- The behind-the-scenes chaos of selling out every drop — from supplier delays to warehouses bursting at the seams.
- The power of taking fast action, even when you’re scared, and why “money loves speed” became their golden rule.
- How Coastal GRL went from a small apartment start-up to one of Australia’s fastest-growing haircare brands in under a year.
