Tangles, dryness, dandruff, oily scalps – these are all common hair woes we’d love to wash down the drain. And Hair Syrup founder Lucie Macleod knew these problems all too well.

Having struggled with damaged hair in her final year of university, Macleod was on the hunt for a product to help restore its strength and shine.

But after scouring the high street, she found that most treatments were either too expensive for everyday shoppers, or offered formulas that lacked natural ingredients and didn’t actually do what they promised.

Macleod’s unsuccessful search sparked the idea to start her own haircare brand – one that offers natural haircare without the hefty price tag. Following Hair Syrup’s launch on social media, demand for the products grew faster than Macleod could make them.

Friends and family were eager to try her formula, and when her first TikTok video gained over 500,000 views and thousands of comments, she was bombarded with requests to try her products – turning what was once a simple side hustle into a solid business opportunity.

Building on her viral success, Macleod took her brand to the national stage by appearing on Series 22 of the BBC show Dragons’ Den, though she failed to secure investment.

However, despite the Dragons’ rejection – with guest judge Trinny Woodall commenting that she didn’t “invest in trends” – Macleod wasn’t deterred. Thanks to this appearance, the Welsh brand went on to partner with major retailers, including Boots and Superdrug.

Today, Hair Syrup is one of the most successful TikTok brands – where it has 436.3K followers – plus it has increased its turnover from £120K in 2022 to a hair-raising £5m.

At just 26, Macleod’s resilience and natural flair for digital marketing left a strong impression on our judges. We’re thrilled to welcome the business to this year’s list and to bestow Hair Syrup with a nomination for the Startups 100 Marketing Award for 2026.
