Elsha Bulmer, Jenna Willis and Morgan Passey from Otago Girls High School have taken out this year's top prize at the Young Enterprise Scheme Awards.
They created a colour-matching dry shampoo offering sun protection - particularly for the scalp.
The trio's company, Sole, has sold over 500 products marketed via TikTok. Their enterprise has resulted in each of them winning a $5-thousand dollar scholarship to the Massey University Business School.
