Iles Formula is a collection of luxury, award-winning, clean, and botanically derived formulas, meticulously designed to revive hair and scalp health.

Founded and formulated by renowned hairstylist Wendy Iles, the collection offers a refreshing counterpoint to an oversaturated haircare market—delivering phenomenal, salon-grade performance backed by clinically proven results. Trusted by elite salons globally and celebrated by the most respected beauty authorities, including Allure (Best of Beauty), Harper’s Bazaar, Marie Claire, SheFinds, and Oprah Beauty, Iles Formula sets the global standard for performance without compromise.

The original three signature formulas—Shampoo, Conditioner, and Finishing Serum—were first developed for Wendy’s personal use in her work with celebrity and royal clientele. Today, the collection is formulated for all hair types and is particularly revered for its transformative results on compromised and damaged hair, as well as hair experiencing thinning or loss.

Crafted under the principles of Positive Luxury, each formula is vegan-friendly, never tested on animals, and intentionally created to deliver exceptional results with integrity. Innovative, curated, and quietly iconic, Iles Formula is an if-you-know-you-know brand—loved by those who expect nothing less than excellence.

“I have always been passionate for lustrous, healthy hair. It's just part of the DNA of my approach to hairdressing. Iles Formula is a natural extension of this approach that I’ve bottled and share with you all.”

- Wendy Iles, Founder of Iles Formula
