Shu Uemura Ultimate Reset Serum - 90ml

No, this is a leave-in treatment. It is designed to be absorbed by your hair overnight.

The manufacturer recommends applying this serum to dry hair for optimal absorption.

You can use it as needed, especially when your hair feels particularly dry or brittle from styling.

Yes, the Ultimate Reset line is generally safe for color-treated hair, but always perform a patch test if you have specific concerns.

Since you only need a small amount per application, a 90ml bottle should last for several months of regular use.

You may be using too much product. Try reducing the amount to a pea-sized drop and focus application strictly on the ends.

Ensure the cap is clean and wipe the nozzle with a warm, damp cloth to remove any dried residue that may be obstructing the flow.
