Should I apply hair serum or hair oil first?

In general, you apply hair serum first and then hair oil. A serum is usually lighter and helps to target specific concerns such as frizz or improving shine by penetrating the hair fiber. Oil is heavier and helps seal the hair cuticle, preventing moisture loss and protecting the hair.

It is often recommended to use hair serum first because it is lighter and can penetrate the hair more effectively. Hair oil is heavier and seals the cuticle, which is ideal for protecting the hair and locking in moisture. Make sure your hair is dry or towel-dried before applying both products so they can work optimally.
