Tech start-up Rock Pamper Scissors has closed a £1.2m investment round from venture capital groups 500 Startups and Seedcamp, alongside a group of angel investors.
The app is available on iOS and Android and offers users a chance to view available appointments from salons across the city and also see examples of their work.
The funding will be used to grow stylist and client usage in London, having successfully tested its approach in Leeds and Manchester throughout last year.
It will also help strengthen the company's tech team and continue its development of apps and services looking to shake-up the stylist community.
Founder Mat Braddy said: “Whilst building Just Eat it really puzzled me that no-one had built an excellent app for haircut booking.
“We believe less than 1% of haircuts are currently booked online - that's insane. By focusing our brand and thinking on the millennial consumers, Uber’s children, who require instant access to services right now, we believe we have come up with a compelling approach which will finally solve this dilemma.”
Angel investor Tom Singh OBE added: “Over the past few years I’ve had many fashion apps presented to me, but Rock Pamper Scissors stands out.
“It clearly disrupts an outdated way in which bookings for haircuts can be made, by facilitating choice and with complete ease.
“In my opinion, it’s only a matter of time before calling for hair appointments will be a thing of the past - why would you when an app like this enables informed, fast and easy bookings?”
The business based at The Pill Box in East London is led by experienced entrepreneur Bertie Cordingley, founder of fillmybelly.com - a food delivery service bought by Just Eat in 2012, with co-founders Mat Braddy (ex-CMO Just Eat), Chris Osborne (ex-FT.com product lead),and Paula Fanning (ex-head of design for ITV.com).
