Your go-to styling serum, protecting against heat, UV,  humidity & colour fade.

There's no better way to protect all hair types from environmental assaults than with the signature Finishing Serum. Hand-picked, custom blended ingredients including vitamins, nut oils, silk, and ceramide, feed hair with nothing but goodness without ever weighing it down. This paraben free formula creates a screen against UV rays, humidity and free radicals: strengthening hair + helping repair split ends + preventing colour fade. Lightly scented with white flowers.

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.

How to use

Finishing Serum can be applied to both wet and dry hair. Ideally use after using Iles Formula Shampoo and Conditioner. Apply small amount to each section on wet hair as you blow-dry. This will make thin hair feel thicker and calms thick coarse hair. Apply small amount daily to dry hair to protect against heated tools, UV damage, colour fade and humidity.
