Frequently Asked Questions

What is hair serum used for?

Hair serum helps protect and smooth the lengths: it reduces frizz, adds shine, seals the ends, and protects against heat and humidity. Many serums contain lightweight silicones or plant oils that coat the hair fiber without weighing it down. It is ideal for dry, frizzy, or damaged hair.

When should hair serum be applied?

Hair serum should be applied to damp or dry hair from mid-lengths to ends. On damp hair, apply before'drying, or on dry hair as a finishing touch. Applied to damp hair, it helps detangle and protects against heat; on dry hair, it tames frizz and adds shine. Avoid applying it to the roots to prevent weighing the hair down.

How do you use hair serum?

To use the hair serum, warm 1-2 drops between the palms of your hands and distribute through the lengths and ends, avoiding the roots. It can be applied to damp hair before styling or to dry hair to eliminate frizz. The amount should be adjusted to the length and thickness of the hair.

What’s the difference between hair serum and hair oil?

Hair serum has a lightweight texture and often contains silicones or polymers that coat the hair fiber, protecting it and making it shiny and manageable. L'hair oil is more nourishing, made with plant-based oils, and penetrates the fiber to nourish and soften it. Serum is better suited for styling, o'il for treatment.
