Answer first
The best time is the one you will stick to. Many people apply Folli-Fix at night after a shower so it dries before bed, while others prefer the morning before styling. Women use it once daily; follow the pack for men. Allow it to dry before lying down or wearing a cap.
Night
Fits after an evening shower. Let it dry fully to avoid transfer onto pillows.
Morning
Apply before styling; keep styling products on the hair.
