The Iles Formula Finishing Serum is a great favorite of freelance hairdressers on a professional photo or film shoot. It's where most of our huge celebrity following first experienced Iles Formula. This formula has the power to transform dry, brittle hair to sumptuous silk just by blow drying it in to wet hair. It has heat protection, UV and humidity protection, all without ever weighing the hair down. It delivers a memory to the hair that changes form as you ask of it, and lastly it delivers the most expensive looking lustrous shine.
