The grand spectacle, dubbed Hair Color Coders 2025, saw 422 hairstylists and 422 models take over a 1 lakh sq ft space, powered by 60 backwashes and more than 5,000 tubes of colour. The palette of the day? Iconic Browns, the brand’s colour trend of the year versatile tones designed to capture India’s evolving love affair with understated glamour.

The day was anchored by Min Kim, L’Oréal Professionnel’s Global Color Ambassador, who demonstrated cutting-edge techniques like face-framing and tonal layering.

She underlined how premium salon services like hair colour are now driving unprecedented growth, with salons morphing into destinations for personalised, elevated experiences.
The record-breaking showcase was the culmination of four intensive pre-event masterclasses where hairdressers were trained in not just cut, colour and style but also social savviness ensuring their artistry resonates both in salons and online feeds. “Education has been the backbone of our brand,” said Priya Kasthuri Rangan, Head of Education, L’Oréal Professionnel India. “Hair Color Coders wasn’t only about setting a record, it was about equipping stylists with the skills and confidence to shine as creators.”
